rtc: s35390a: Change buf's type to u8 in s35390a_init
Clang warns: drivers/rtc/rtc-s35390a.c:124:27: warning: implicit conversion from 'int' to 'char' changes value from 192 to -64 [-Wconstant-conversion] buf = S35390A_FLAG_RESET | S35390A_FLAG_24H; ~ ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~ 1 warning generated. Update buf to be an unsigned 8-bit integer, which matches the buf member in struct i2c_msg. https://github.com/ClangBuiltLinux/linux/issues/145 Signed-off-by: Nathan Chancellor <natechancellor@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
