Subject: [PATCH v2 3/6] spi: microchip-core: Replace dead code (-ENOMEM error message)
Date: Wed, 26 Nov 2025 08:54:41 +0100 [thread overview]
Message-ID: <20251126075558.2035012-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20251126075558.2035012-1-andriy.shevchenko@linux.intel.com>
First of all, the convention in the kernel that we do not issue
error messages for -ENOMEM. Second, it's ignored by dev_err_probe().
Replace dead code by a simple return statement.
