staging: fbtft: remove redundant license text

2018-01-15T15:03:46Z

Now that the SPDX tag is in all fbtft files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

staging: fbtft: add SPDX identifiers

2018-01-15T15:03:46Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Fix up the all of the staging fbtft drivers to have a proper SPDX identifier, based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

staging: fbtft: change 'gamma' array to u32

2017-02-03T12:01:36Z

Having a local variable of 1024 bytes on 64-bit architectures is a bit too much, and I ran into this warning while trying to see what functions use the largest stack: drivers/staging/fbtft/fbtft-sysfs.c: In function 'store_gamma_curve': drivers/staging/fbtft/fbtft-sysfs.c:132:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=] As there is no need for 64-bit gamma values (on 32-bit architectures, we don't use those either), I'm changing the type from 'unsigned long' to 'u32' here, which cuts the required space in half everywhere.

Staging: fbtft: fix header guard typo

2015-04-30T14:51:21Z

drivers/staging/fbtft/internal.h header guard tests for __LINUX_FBTFT__INTERNAL_H but then defines __LINUX_FBTFT_INTERNAL_H (only 1 underscore) and uses the same name for the #endif comment. Use the same name everywhere. Signed-off-by: Nicolas Iooss Signed-off-by: Greg Kroah-Hartman

Staging: fbtft: add header for internal functions

2015-03-07T00:44:13Z

Remove extern keyword from function prototypes to suppress warning from checkpatch.pl with --strict option: https://lkml.org/lkml/2013/7/23/422 fbtft maintainer Noralf Tronnes advised these functions are internal to this module & suggested moving these prototypes to new internal.h file. He also advised fbtft.h file will eventually live in include/linux/fbtft.h Suggested-by: Noralf Trønnes Signed-off-by: Drew Fustini Signed-off-by: Greg Kroah-Hartman
