Subject: [PATCH v1 02/10] xhci: dbc: Convert to use sysfs_streq()
Date: Mon, 2 Oct 2023 19:16:02 +0300 [thread overview]
Message-ID: <20231002161610.2648818-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231002161610.2648818-1-andriy.shevchenko@linux.intel.com>
It's standard approach to parse values from user space by using
sysfs_streq(). Make driver use it.
