Subject: gpio: omap: irq_shutdown: remove unnecessary call of gpiochip_unlock_as_irq
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=878ce05894284d3eb683e7d249d09c796c02d73b;p=linux-beck.git

gpio: omap: irq_shutdown: remove unnecessary call of gpiochip_unlock_as_irq

GPIOLib core implemnts irqchip->irq_request/release_resources callbacks
internally and these callbacks already contain clalls of
gpiochip_lock/unlock_as_irq().

Hence, remove unnecessary call of gpiochip_unlock_as_irq() from
omap_gpio_irq_shutdown().
