gpio: omap: clean up edge interrupt handling
The edge interrupt handling was effectively:
isr = ISR_reg & enabled;
if (bank->level_mask)
level_mask = bank->level_mask & enabled;
else
level_mask = 0;
edge = isr & ~level_mask;
When bank->level_mask is zero, level_mask will be computed as zero
anyway, so the if() statement is redundant. We are then left with:
isr = ISR_reg & enabled;
level_mask = bank->level_mask & enabled;
edge = isr & ~level_mask;
This can be simplified further to:
isr = ISR_reg & enabled;
edge = isr & ~bank->level_mask;
since the second mask with 'enabled' is redundant.
Improve the associated comment as well.
