Subject: [PATCH v2 5/5] gpiolib: Move error message out of a spinlock
Date: Fri, 8 Apr 2022 21:18:54 +0300 [thread overview]
Message-ID: <20220408181854.73528-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220408181854.73528-1-andriy.shevchenko@linux.intel.com>
An error path is a slow path, no need to block other CPUs
when printing error messages.
