power: supply: Remove unnecessary print function dev_err()

[PATCH -next] power: supply: Remove unnecessary print function dev_err()

Posted by Yang Li 4 years ago

The print function dev_err() is redundant because
platform_get_irq() already prints an error.

Eliminate the follow coccicheck warning:
./drivers/power/supply/goldfish_battery.c:225:2-9: line 225 is
redundant because platform_get_irq() already prints an error
