Subject: sunrpc: do not pin sunrpc module in the memory
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c9f6cde6e26ef98ee9c4b6288b126ac9c580d88b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sunrpc: do not pin sunrpc module in the memory

Basically, try_module_get here are pretty useless. Any other module using
this API will pin sunrpc in memory due using exported symbols.
