Subject: [PATCH v2 4/5] extcon: Use sizeof(*pointer) instead of sizeof(type)
Date: Wed,  5 Apr 2023 18:27:44 +0300	[thread overview]
Message-ID: <20230405152745.24959-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230405152745.24959-1-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.
