Subject: [PATCH 09/19] xhci: dbc: Use sizeof(*pointer) instead of sizeof(type)
Date: Fri,  1 Dec 2023 17:06:37 +0200	[thread overview]
Message-ID: <20231201150647.1307406-10-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20231201150647.1307406-1-mathias.nyman@linux.intel.com>

From: Andy Shevchenko <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.
