| |
Until now the aforementioned return value has been ignored. Previous and current calls to tps65217_reg_read() return instantly when the value is not 0, so let's do that.
Fixes the following W=1 warning:
drivers/regulator/tps65217-regulator.c: In function ‘tps65217_regulator_probe’: drivers/regulator/tps65217-regulator.c:227:9: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] 227 | int i, ret; | ^~~
