Subject: mfd: rtsx: Simplify function return logic
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b158b69a37651b20a0e68f89cf118461e7de4872;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mfd: rtsx: Simplify function return logic

The invoked functions already return zero on success or a negative
errno code so there is no need to open code the logic in the caller.
