regulator: tps65217-regulator: Use the returned value of tps65217_reg_read()
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; | ^~~ Signed-off-by: Lee Jones <lee.jones@linaro.org> Cc: Russ Dill <Russ.Dill@ti.com> Cc: Keerthy <j-keerthy@ti.com> Cc: AnilKumar Ch <anilkumar@ti.com> Cc: linux-omap@vger.kernel.org Link: https://lore.kernel.org/r/20200626065738.93412-7-lee.jones@linaro.org Signed-off-by: Mark Brown <broonie@kernel.org>
