Subject: [PATCH v4 4/8] iio: core: Calculate alloc_size only once in iio_device_alloc()
Date: Wed, 28 Feb 2024 22:41:34 +0200	[thread overview]
Message-ID: <20240228204919.3680786-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240228204919.3680786-1-andriy.shevchenko@linux.intel.com>

No need to rewrite the value, instead use 'else' branch.
This will also help further refactoring the code later on.
