2021-06-17hwmon: (sht4x) Fix sht4x_read_values return valueJoe Perches1-50/+45
Kernel doc for sht4x_read_values() shows 0 on success, 1 on failure but the return value on success is actually always positive as it is set to SHT4X_RESPONSE_LENGTH by a successful call to i2c_master_recv(). Miscellanea: o Update the kernel doc for sht4x_read_values to 0 for success or -ERRNO o Remove incorrectly used kernel doc /** header for other _read functions o Typo fix succesfull->successful o Reverse a test to unindent a block and use goto unlock o Declare cmd[SHT4X_CMD_LEN] rather than cmd[] At least for gcc 10.2, object size is reduced a tiny bit. $ size drivers/hwmon/sht4x.o* text data bss dec hex filename 1752 404 256 2412 96c drivers/hwmon/sht4x.o.new 1825 404 256 2485 9b5 drivers/hwmon/sht4x.o.old Signed-off-by: Joe Perches <joe@perches.com> Link: https://lore.kernel.org/r/60eedce497137eb34448c0c77e01ec9d9c972ad7.camel@perches.com Reviewed by: Navin Sankar Velliangiri <navin@linumiz.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
