treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

IS_BUILTIN can be use to replace various initializations like #if CONFIG_ int val = 1; #else int val = 0; #endif so do so.

video: omapfb: Use scnprintf() for avoiding potential buffer overflow

2020-03-20T13:29:04Z

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf().

video: fbdev: don't print error message on framebuffer_alloc() failure

2019-06-28T10:30:08Z

framebuffer_alloc() can fail only on kzalloc() memory allocation failure and since kzalloc() will print error message in such case we can omit printing extra error message in drivers (which BTW is what the majority of framebuffer_alloc() users is doing already).

video: fbdev: omapfb: lcd_ams_delta: use GPIO lookup table

2018-10-08T10:57:36Z

Now as Amstrad Delta board - the only user of this driver - provides GPIO lookup tables, switch from GPIO numbers to GPIO descriptors and use the table to locate required GPIO pins. Declare static variables for storing GPIO descriptors and replace gpio_ function calls with their gpiod_ equivalents. Move GPIO lookup to the driver probe function so device initialization can be deferred instead of aborted if a GPIO pin is not yet available. Pin naming used by the driver should be followed while respective GPIO lookup table is initialized by a board init code.
