Fix 20 checkpatch errors.
Among these errors, 18 of them are incorrect space usage, such as:
ERROR: space prohibited after that open parenthesis '('
#128: FILE: drivers/i2c/busses/i2c-iop3xx.c:128:
+ if ( !rc ) rc = -I2C_ERR_BERR
The remaining two errors are trailing statements should be on next line,
such as:
ERROR: trailing statements should be on next line
#128: FILE: drivers/i2c/busses/i2c-iop3xx.c:128:
+ if ( !rc ) rc = -I2C_ERR_BERR;
