Subject: nvme: use UINT_MAX for max discard sectors
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bd0fc2884ca4d1516da1aa5cf44385e24dc23c29;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nvme: use UINT_MAX for max discard sectors

It's more elegant to use UINT_MAX to represent the max value of
type unsigned int. So replace the actual value by using this define.
