Hi all,
After merging the fbdev tree, today's linux-next build (x86_64
allmodconfig) failed like this:
/tmp/next/build/drivers/video/fbdev/aty/aty128fb.c:2027:6: error:
variable 'info' is used uninitialized whenever 'if' condition is true
[-Werror,-Wsometimes-uninitialized]
2027 | if (!pcim_request_region(pdev, 2, "aty128fb MMIO")) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/tmp/next/build/drivers/video/fbdev/aty/aty128fb.c:2096:22: note:
uninitialized use occurs here
2096 | framebuffer_release(info);
| ^~~~
/tmp/next/build/drivers/video/fbdev/aty/aty128fb.c:2027:2: note: remove
the 'if' if its condition is always false
2027 | if (!pcim_request_region(pdev, 2, "aty128fb MMIO")) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2028 | printk(KERN_ERR "aty128fb: cannot reserve MMIO region\n");

2029 | goto err_free_info;

2030 | }

/tmp/next/build/drivers/video/fbdev/aty/aty128fb.c:2001:22: note:
initialize the variable 'info' to silence this warning

Caused by commit
99c188b02c281 (fbdev: aty128fb: Convert to managed PCI and ioremap API)
I have used the tree from next-20260813 instead.
