fbtft: Make sure string is NULL terminated
[ 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.
Make sure string is NULL terminated by switching to snprintf().
