Subject: [PATCH v1 12/14] extcon: Use sizeof(*pointer) instead of sizeof(type)
Date: Wed, 22 Mar 2023 16:40:03 +0200	[thread overview]
Message-ID: <20230322144005.40368-13-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230322144005.40368-1-andriy.shevchenko@linux.intel.com>

It is preferred to use sizeof(*pointer) instead of sizeof(type).
The type of the variable can change and one needs not change
the former (unlike the latter). No functional change intended.
