[ Upstream commit ef0f02fd69a02b50e468a4ddbe33e3d81671e248 ]
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.
