Subject: [PATCH v1 1/1] pinctrl: intel: No need to disable IRQs in the handler
Date:   Thu,  4 Mar 2021 12:54:32 +0200
Message-Id: <20210304105432.36544-1-andriy.shevchenko@linux.intel.com>
MIME-Version: 1.0

Precedence: bulk

In IRQ handler interrupts are already disabled, hence no need
to repeat it. Even in the threaded case, which is disabled here,
it is not a problem because IRQ framework serializes descriptor
handling. Remove disabling IRQ part in the handler.
