Subject: powerpc/fsl_soc: improve and simplify get_baudrate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f236988e9ec13d0ee49f580f945d594bd7989a7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/fsl_soc: improve and simplify get_baudrate

Use of_property_read_u32 instead of the generic of_get_property to
simplify the code. In addition move the declaration of fs_baudrate
into get_baudrate because it's private to this function.
