X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b547bf0cf24a99c57be202ed72f6a46f73d6b61;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

serial: samsung: remove serial_get/setsource function

This patch removes serial_get/setsource function that are not necessary.
On Exynos5 and Exynos7, the number of clk source of baudrate is 1.
That is, "num_clks" is always 1, we don't need to change clock source of
baudrate.
