Subject: [PATCH v3 6/7] gpio: ep93xx: refactor ep93xx_gpio_add_bank
Date: Thu, 28 Jan 2021 15:21:22 +0300 [thread overview]
Message-ID: <20210128122123.25341-7-nikita.shubin@maquefel.me> (raw)
In-Reply-To: <20210128122123.25341-1-nikita.shubin@maquefel.me>
- replace plain numbers with girq->num_parents in devm_kcalloc
- replace plain numbers with girq->num_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>

v2->v3
- use ->num_parents instead of ARRAY_SIZE()
