With a compatible string like compatible = "foo"; checkpatch will currently try to find "foo" in vendor-prefixes.txt, which is wrong since the vendor prefix is empty in this specific case. Skip the vendor test if the compatible is not like compatible = "vendor,something"; Signed-off-by:

The current octal permissions test is very slow. When patch ("checkpatch: add checks for constant non-octal permissions") was added, processing time approximately tripled. Regain almost all of the performance by not looping through all the possible functions unless the line contains one of the functions. Signed-off-by: -

Modify warning message when printk is used in a patch. It mentions to use subsystem_dbg instead of netdev_dbg as the first preferred format of logging debug messages. Signed-off-by:

This test is a bit noisy and opinions seem to agree that it should not warn in a lot more situations. It seems people agree that: return (foo || bar); and return foo || bar; are both acceptable style and checkpatch should be silent about them. For now, it warns on parentheses around a simple constant or a single function or a ternary. return (foo); return (foo(bar)); return (foo ? bar : baz); The last ternary test may be quieted in the future. Modify the deparenthesize function to only strip balanced leading and trailing parentheses. Signed-off-by:

It's very common to have normal block comments for the initial comments of a file description preface. So for files in drivers/net and net/ don't emit a warning when the first comment block in the file uses the normal block comment style and not the networking block comment style. Signed-off-by:

static const char* arrays create smaller text as each function call does not have to populate the array. Emit a warning when char *arrays aren't static const and the array is not apparently global by being declared in the first column. Signed-off-by:

checkpatch could not distinguish between a variable in a struct named jiffies and the normal jiffies. foo->jiffies would emit a "Comparing jiffies" arning. Update the $Compare variable to do a negative look-behind for "-" when finding a ">" so that a pointer dereference like -> isn't a comparison. Signed-off-by:

Emit a warning when using any of these __constant_<foo> forms: __constant_cpu_to_be[x] __constant_cpu_to_le[x] __constant_be[x]_to_cpu __constant_le[x]_to_cpu __constant_htons __constant_ntohs Using any of these outside of include/uapi/ isn't preferred as using the function without __constant_ is identical when the argument is a constant.

umode_t permissions are sometimes mistakenly written with decimal constants. Verify that numeric permissions are using octal. Add a list of the most commonly used functions and macros that have umode_t permissions and the argument position. Add a $Octal type to $Constant. Allow $LvalOrFunc to be a pointer indirection too.

Checks for some function pointer return styles are too strict. Fix them. Multiple spaces after function pointer return types are allowed. int (*foo)(int bar) Spaces after function pointer returns of pointer types are not required. int *(*foo)(int bar) Signed-off-by:

Holger reported: : The macro udelay cannot handle large values because of loss-of-precision. : : IMHO udelay on ARM is broken, because it also cannot work with fast : ARM processors (where bogomips >= 3355, which is in sight now). It's : just not broken enough that someone did something against it ... so : the current kludge is good enough. Until then, warn on long udelay uses. Also fix uses of $line that should have been $herecurr. Signed-off-by:

Include appropriate header file include/linux/decompress/inflate.h in lib/decompress_inflate.c because it has prototype declaration of function defined in lib/decompress_inflate.c. Also, fix the guard around the header file include/linux/decompress/inflate.h to use a more unique guard symbol. This avoids conflict with the INFLATE_H defined by zlib_inflate/inflate.h. This eliminates the following warning in lib/decompress_inflate.c: lib/decompress_inflate.c:35:17: warning: no previous prototype for `gunzip' [-Wmissing-prototypes] Signed-off-by:

Add prototype declarations of functions in lib/clz_ctz.c. These functions are required by GCC builtins and hence can not be removed despite of their unreferenced appearance in kernel source.

These are just some very minor and misc cleanups in the PRNG. In prandom_u32() we store the result in an unsigned long which is unnecessary as it should be u32 instead that we get from prandom_u32_state(). prandom_bytes_state()'s comment is in kdoc format, so change it into such as it's done everywhere else. Also, use the normal comment style for the header comment. Last but not least for readability, add some newlines. Signed-off-by:

Having a discussion about sparse warnings in the kernel, and that we should clean them up, I decided to pick a random file to do so. This happened to be devres.c which gives the following warnings: CHECK lib/devres.c lib/devres.c:83:9: warning: cast removes address space of expression lib/devres.c:117:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:117:31: expected void [noderef] <asn:2>* lib/devres.c:117:31: got void * lib/devres.c:125:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:125:31: expected void [noderef] <asn:2>* lib/devres.c:125:31: got void * lib/devres.c:136:26: warning: incorrect type in assignment (different address spaces) lib/devres.c:136:26: expected void [noderef] <asn:2>*[assigned] dest_ptr lib/devres.c:136:26: got void * lib/devres.c:226:9: warning: cast removes address space of expression Mostly it's just the use of typecasting to void * without adding __force, or returning ERR_PTR(-ESOMEERR) without typecasting to a __iomem type. I added a helper macro IOMEM_ERR_PTR() that does the typecast to make the code a little nicer than adding ugly typecasts to the code.

We don't have to update a backlight status every time a blanking or unblanking event comes because the backlight status may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. We don't hope blanking one of the framebuffers may turn the backlight off for all the other framebuffers, since they are likely being active to display something. This patch makes the backlight status be updated only when the relevant backlight device's use count changes from zero to one or from one to zero. Signed-off-by:

We don't have to update the state and fb_blank properties of a backlight device every time a blanking or unblanking event comes because they may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. The backlight driver should take the backlight device as a resource shared by all the associated framebuffers. This patch adds some logic to record each framebuffer's backlight usage to determine the backlight device use count and whether the two properties should be updated or not. To be more specific, only one unblank operation on a certain blanked framebuffer may increase the backlight device's use count by one, while one blank operation on a certain unblanked framebuffer may decrease the use count by one, because the userspace is likely to unblank an unblanked framebuffer or blank a blanked framebuffer.
