2018-01-15staging: fbtft: remove redundant license textGreg Kroah-Hartman1-10/+0
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.

2018-01-15staging: fbtft: add SPDX identifiersGreg Kroah-Hartman1-0/+1
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.

2016-10-16staging: fbtft: Convert int arrays to s16Joe Perches1-1/+1
These arrays use -1, -2, and -3 as initiators for various types of writes to initialize hardware. No values are used that conflict with using these arrays as s16 instead of int and reducing overall data is good. $ size drivers/staging/fbtft/built-in.o* text data bss dec hex filename 116120 32872 4152 153144 25638 drivers/staging/fbtft/built-in.o.new 116104 36344 6200 158648 26bb8 drivers/staging/fbtft/built-in.o.old Miscellaneous: o Realign some of the arrays to make reading a bit easier Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
