It would be nice to check return value here and print some message on error,
as unlike hx4700_gpio_request, gpio_request_array() is completely silent.

No space between pr_err and (.

Does the return code convey useful information as to _why_ it failed?  If
yes, you really should print its value.  Knowing whether it's -EBUSY
(eg, already in use) instead of -EINVAL (eg, invalid GPIO number) really
helps to debug problems.

checkpatch issue. Sorry about that.

Yes, it does. It is certainly better to include the error code.
Recompiling with DEBUG_GPIO enabled might still be necessary to get
information about which GPIO failed, and whether -EINVAL was returned
by gpio_request() or gpio_direction_input/output().
