[PATCH v1 09/10] xhci: dbc: Use sizeof(*pointer) instead of sizeof(type)

From: Andy Shevchenko
Date: Mon Oct 02 2023 - 12:19:31 EST


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.
