* staging: fbtft: remove redundant license textGreg Kroah-Hartman2018-01-151-10/+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.

* staging: fbtft: add SPDX identifiersGreg Kroah-Hartman2018-01-151-0/+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.

* staging: fbtft: remove redundant initialization of bufColin Ian King2017-11-061-1/+1
| | | | | | | | | | | The pointer buf is being set on each iteration of a for-loop and so the initialization of buf at declaration time is redundant and can be removed. Cleans up clang warning: drivers/staging/fbtft/fb_uc1701.c:130:6: warning: Value stored to 'buf' during its initialization is never read Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* staging: fbtft: use alternate screen pointerLars Svensson2015-10-131-1/+1
| | | | | | | | | | Member screen_base in struct fb_info is declared with __iomem qualifier causing sparse warnings when used as a regular ponter. To avoid the warnings, instead use alternate non-__iomem pointer, screen_buffer, troughout the driver.

* Staging: fbtft: clean dev_err() loggingHaneen Mohammed2015-03-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes __func__ from dev_err. dev_err includes information about: (devcice, driver, specific instance of device, etc) in the log printout. This was done using Coccinelle, with the following semantic patch: @a@ expression E, R; expression msg; @@ dev_err(E, msg, __func__, R); @script:python b@ e << a.msg; y; @@ if(e.find("%s: ") == True): m = e.replace("%s: ", "", 1); coccinelle.y = m; elif(e.find("%s ") == True): m = e.replace("%s ", "", 1); coccinelle.y = m; elif(e.find("%s:") == True): m = e.replace("%s:", "", 1); coccinelle.y = m; else: m = e.replace("%s", "",1); coccinelle.y = m; @c@ expression a.E, a.msg, a.R; identifier b.y; @@ - dev_err(E, msg, __func__, R); + dev_err(E, y, R); Signed-off-by: Haneen Mohammed <hamohammed.sa@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
