i2c: iop3xx: Fix coding style issues
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; No functional changes.
