| | | | | | | | | | | | | | | | | | | [ Upstream commit 21f585480deb4bcf0d92b08879c35d066dfee030 ] New GCC warns about inappropriate use of strncpy(): drivers/staging/fbtft/fbtft-core.c: In function ‘fbtft_framebuffer_alloc’: drivers/staging/fbtft/fbtft-core.c:665:2: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation] 665 | strncpy(info->fix.id, dev->driver->name, 16); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Later on the copy is being used with the assumption to be NULL terminated.

* Staging: fbtft: fix memory leak in fbtft_framebuffer_allocNavid Emamdoost2019-10-171-2/+5
| | | | | | | | | | | | | | | | | [ Upstream commit 5bdea6060618cfcf1459dca137e89aee038ac8b9 ] In fbtft_framebuffer_alloc the error handling path should take care of releasing frame buffer after it is allocated via framebuffer_alloc, too. Therefore, in two failure cases the goto destination is changed to address this issue.

* | | staging: fbtft: fix voltage settings for C-Berry28Dennis Menschel2015-10-241-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes some internal voltage settings for the C-Berry28 display. The original example source files for the C-Berry28 as provided by its vendor admatec contained six issues where a command parameter's value didn't match its corresponding comment. I've informed admatec about these discrepancies on 2015-08-25. In the meantime, I've assumed the comments to be more reliable than the code, and thus have used these values to write the initial C-Berry28 driver. After having received a reply from admatec on 2015-10-16 that the issues have been fixed in their example code, it has turned out that for the voltages VCOM and AVDD, the code was indeed correct, but the comments were wrong. This patch is meant to fix these two pending mistakes. Signed-off-by: Dennis Menschel <menschel-d@posteo.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
