X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=65da4d81f48e092f71feaf04bf2ccd096b5a5171;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] ioremap balanced with iounmap for drivers/serial/sunsu.c

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.
