Subject: fbdev: nvidiafb: Correct const string length in nvidiafb_setup()
X-Git-Tag: v6.16-rc1~93^2~7
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=34fe05cd2d0f4cc625afb656469a9838f02ca59e;p=linux-block.git

fbdev: nvidiafb: Correct const string length in nvidiafb_setup()

The actual length of const string "noaccel" is 7, but the strncmp()
branch in nvidiafb_setup() wrongly hard codes it as 6.

Fix by using actual length 7 as argument of the strncmp().
