Subject: rtc: ds1302: fix error check in set_time
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc83a141b8351f6d4458dd13eca5a66f2c0f3323;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rtc: ds1302: fix error check in set_time

The set_time callback for rtc-ds1302 doesn't write clock registers
because the error check for the return value from spi_write_then_read()
is not correct.  spi_write_then_read() which returns zero on success.
