Subject: [PATCH v2 7/8] gpiolib: Reuse return variable in gpiod_to_irq()
Date: Wed, 16 Apr 2025 12:55:15 +0300	[thread overview]
Message-ID: <20250416095645.2027695-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20250416095645.2027695-1-andriy.shevchenko@linux.intel.com>

There are two variables for the same used in the gpiod_to_irq().
Replace the second by reusing the function top-level one.
While at it, refactor the branch to have less lines of code.
