- replace plain numbers with girq->num_parents in devm_kcalloc - replace plain numbers with ARRAY_SIZE(girq->parents) for port F - refactor i - 1 to i + 1 to make loop more readable - combine getting IRQ's loop and setting handler's into single loop Signed-off-by: Nikita Shubin <nikita.shubin@maquefel.me> --- drivers/gpio/gpio-ep93xx.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-)
