[PATCH v3 8/8] gpiolib: use %*pb format specifier when printing array masks

[Dmitry Torokhov]

In gpiod_get_array(), the dev_dbg() statement prints get_mask, set_mask,
and invert_mask using %lx after dereferencing them as raw unsigned long
pointers. This truncates masks wider than BITS_PER_LONG to their first
word and relies on the raw unsigned long pointer representation of
bitmaps.

Switch to the %*pb format specifier, passing the mask size and pointer
for each mask.
