Because dev_*() are used along with pr_debug() function in this code, the debug message is not tidy. This patch converts from pr_debug() to dev_dbg() since dev_*() are encouraged to use in device driver code. Signed-off-by:

Driver core clears the driver data to NULL after device_release or on probe failure, so just remove it from here. The relevant driver core change was commit 0998d063 ("device-core: Ensure drvdata = NULL when no driver is bound"). Signed-off-by:

The variable want_irq is only assigned the values true and false. Change its type to bool. The simplified semantic patch that find this problem is as follows (http://coccinelle.lip6.fr/): @exists@ type T; identifier b; @@ - T + bool b = ...; ... when any b = \(true\|false\) Signed-off-by:

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by:

When expert configuration option(CONFIG_EXPERT) is enabled, menuconfig offers a choice of compression algorithm to compress initial ramfs image; This choice is stored into CONFIG_RD_* variables. But usr/Makefile uses earlier INITRAMFS_COMPRESSION_* macros to build initial ramfs file. Since none of them is defined, resulting 'initramfs_data.cpio' file remains un-compressed. This patch updates the Makefile to use CONFIG_RD_* variables and adds support for LZ4 compression algorithm. Also updates the 'gen_initramfs_list.sh' script to check whether a selected compression command is accessible or not. And fall-back to default gzip(1) compression when it is not. Signed-off-by:

This patch proposes to make init failures more explicit. Before this, the "No init found" message didn't help much. It could sometimes be misleading and actually mean "No *working* init found". This message could hide many different issues: - no init program candidates found at all - some init program candidates exist but can't be executed (missing execute permissions, failed to load shared libraries, executable compiled for an unknown architecture...) This patch notifies the kernel user when a candidate init program is found but can't be executed. In each failure situation, the error code is displayed, to quickly find the root cause. "No init found" is also replaced by "No working init found", which is more correct. This will help embedded Linux developers (especially the newcomers), regularly making and debugging new root filesystems. Credits to Geert Uytterhoeven and Janne Karhunen for their improvement suggestions. Signed-off-by:

Make menuconfig allows one to choose compression format of an initial ramdisk image. But this choice does not result in duly compressed initial ramdisk image. Because - $ make install - does not pass on the selected compression choice to the dracut(8) tool, which creates the initramfs file. dracut(8) generates the image with the default compression, ie. gzip(1). If a user chose any other compression instead of gzip(1), it leads to a crash due to NULL pointer dereference in crd_load(), caused by a NULL function pointer returned by the 'decompress_method()' routine. Because the initramfs image is gzip(1) compressed, whereas the kernel knows only to decompress the chosen format and not gzip(1). This patch replaces the crash by an explicit panic() call with an appropriate error message. This shall prevent the kernel from eventually panicking in: init/do_mounts.c: mount_block_root() with -> panic("VFS: Unable to mount root fs on %s", b); [akpm@linux-foundation.org: mention that the problem is with the ramdisk, don't print known-to-be-NULL value] Signed-off-by: -
