Subject: parport: "dev->timeslice" is an unsigned long, not an int
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=60af880339aae440293a0c8e93178fdcb41f8a29;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

parport: "dev->timeslice" is an unsigned long, not an int

While auditing proc_doulongvec_ms_jiffies_minmax() usage in kernel, I found
a bug in drivers/parport/procfs.c, incorrectly using sizeof(int) instead of
sizeof(unsigned long)

Only 64bit arches are affected by this old bug.
