Subject: tty: serial: 8250_mtk: remove unnecessary test
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59f89f21b5f34b50584a218734d2b9cc1efd8c0c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tty: serial: 8250_mtk: remove unnecessary test

When the driver has probed successfully the clk pointer is always valid,
so no need to test for it.
