Fix three typos (originally) introduced by commit a9a84c37 ("atmel_lcdfb: backlight control"). Two of these typos were introduced in v2.6.25. (The third was introduced in 915190f7 ("[ARM] 5614/1: at91: atmel_lcdfb: add at91sam9g10 support to atmel LCD driver")). Checking these commits reveals that the default value of 'y' has never been set automatically in all releases since v2.6.25! Perhaps this line might as well be dropped. Signed-off-by:

Add missing braces to include error message. The error message is related to the return value for sysfs_create_group(). However, sysfs_create_group() is called when pdata->en_ambl_sens is not zero. Thus, the checking return value should be included in the if statement. Signed-off-by:

Stephen Warren authored
Create a new N: entry type in MAINTAINERS which performs a regex match against filenames; either those extracted from patch +++ or --- lines, or those specified on the command-line using the -f option. This provides the same benefits as using a K: regex option to match a set of filenames (see commit eb90d085 "get_maintainer: allow keywords to match filenames"), but without the disadvantage that "random" file content, such as comments, will ever match the regex. Hence, revert most of that commit. Switch the Tegra entry from using K: to N: [akpm@linux-foundation.org: fix typo in docs, per Marcin] Reported-by:

Commit 7ff9554b ("printk: convert byte-buffer to variable-length record buffer") removed start and end parameters from call_console_drivers, but those parameters still exist in include/trace/events/printk.h. Without start and end parameters handling, printk tracing became more simple as: trace_console(text, len); Signed-off-by:

This driver requests and remaps a memory region as configured in the device tree. It serves memory from this region via the genalloc API. It optionally enables the SRAM clock. Other drivers can retrieve the genalloc pool from a phandle pointing to this drivers' device node in the device tree. The allocation granularity is hard-coded to 32 bytes for now, to make the SRAM driver useful for the 6502 remoteproc driver. There is overhead for bigger SRAMs, where only a much coarser allocation granularity is needed: At 32 bytes minimum allocation size, a 256 KiB SRAM needs a 1 KiB bitmap to track allocations.

This patch adds three exported functions to lib/genalloc.c: devm_gen_pool_create, dev_get_gen_pool, and of_get_named_gen_pool. devm_gen_pool_create is a managed version of gen_pool_create that keeps track of the pool via devres and allows the management code to automatically destroy it after device removal. dev_get_gen_pool retrieves the gen_pool for a given device, if it was created with devm_gen_pool_create, using devres_find. of_get_named_gen_pool retrieves the gen_pool for a given device node and property name, where the property must contain a phandle pointing to a platform device node. The corresponding platform device is then fed into dev_get_gen_pool and the resulting gen_pool is returned.
