Subject: [PATCH v2 3/8] gpiolib: Print actual error when descriptor contains an error pointer
Date: Wed, 16 Apr 2025 12:55:11 +0300 [thread overview]
Message-ID: <20250416095645.2027695-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20250416095645.2027695-1-andriy.shevchenko@linux.intel.com>
Print the actual error when descriptor contains an error pointer.
This might help debugging those rare cases.
