CVE-2024-53081: media: ar0521: don't overflow when checking PLL values
In the Linux kernel, the following vulnerability has been resolved:
media: ar0521: don't overflow when checking PLL values
The PLL checks are comparing 64 bit integers with 32 bit ones, as reported by Coverity. Depending on the values of the variables, this may underflow.
Fix it ensuring that both sides of the expression are u64.
