[PATCH] rtc: fix a missing check of block data read

2018-12-25 Thread Kangjie Lu
When i2c_smbus_read_i2c_block_data() fails, the read data in "buf" could be incorrect and should not be used. The fix checks if i2c_smbus_read_i2c_block_data fails, and if so, return its error code upstream. Signed-off-by: Kangjie Lu --- drivers/rtc/rtc-hym8563.c | 2 ++ 1 file changed, 2 insert
