Subject: [PATCH v2 09/11] mfd: intel_soc_pmic_bxtwc: Use sysfs_emit() instead of sprintf()
Date: Wed, 29 Jun 2022 01:17:45 +0300 [thread overview]
Message-ID: <20220628221747.33956-9-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220628221747.33956-1-andriy.shevchenko@linux.intel.com>
sysfs_emit() is preferred over sprintf() when formatting the value to be
returned to user space in show() functions, because it knows about sysfs
buffer specifics and has sanity checks.
