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 Signed-off-by: Alexandre Belloni --- drivers/rtc/rtc-s35390a.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers') diff --git a/drivers/rtc/rtc-s35390a.c b/drivers/rtc/rtc-s35390a.c index 77feb603cd4c..3c64dbb08109 100644 --- a/drivers/rtc/rtc-s35390a.c +++ b/drivers/rtc/rtc-s35390a.c @@ -108,7 +108,7 @@ static int s35390a_get_reg(struct s35390a *s35390a, int reg, char *buf, int len) static int s35390a_init(struct s35390a *s35390a) { - char buf; + u8 buf; int ret; unsigned initcount = 0; -- cgit v1.2.3-59-g8ed1b
