Need help determining if the change is warranted.

[Anton Gusev]

In the file drivers/leds/flash/leds-lm3601x.c, function 
lm3601x_strobe_set, the calls to regmap_update_bits aren't checked for 
errors.

I am unsure whether adding the checks is warranted, since 
lm3601x_read_faults might cover the conditions that can cause 
regmap_update_bits to fail there. On the other hand, if this is not 
true, then lm3601x_strobe_set can fail silently. Also, all other calls 
to regmap_update_bit in the driver are checked or directly returned.
