staging: fbtft: core: fix potential memory leak in fbtft_probe_common()

2025-12-18T12:55:06+00:00

[ Upstream commit 47d3949a9b04cbcb0e10abae30c2b53e98706e11 ] fbtft_probe_common() allocates a memory chunk for "info" with fbtft_framebuffer_alloc(). When "display->buswidth == 0" is true, the function returns without releasing the "info", which will lead to a memory leak. Fix it by calling fbtft_framebuffer_release() when "display->buswidth == 0" is true.

[ Upstream commit eb2cb7dab60f9be0b435ac4a674255429a36d72c ] In the error paths after fb_info structure is successfully allocated, the memory allocated in fb_deferred_io_init() for info->pagerefs is not freed. Fix that by adding the cleanup function on the error path.

staging: fbtft: Use backlight power constants

Replace FB_BLANK_ constants with their counterparts from the backlight subsystem. The values are identical, so there's no change in functionality or semantics.

Pull staging driver updates from Greg KH: "Here is the big set of staging driver changes for 6.10-rc1. Not a lot of cleanups happening this kernel release, intern applications must be out of sync at the moment. But we did delete two drivers, wlan-ng and pi433, as they are no longer in use and the developers involved wanted them just gone entirely, allowing us to drop 19k lines from the tree. Other than the normal coding style cleanups here, there has been a lot of work on the vc04_services code, with the intent to finally get that out of staging hopefully soon. It's getting closer, which is nice to see.
