Subject: [PATCH] ath10k: Use sdio_release_host() call only once in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 20 Sep 2024 15:36:19 +0200

A sdio_release_host() call was immediately used after a return code check
in two function implementations.
Thus use such a function call only once instead directly before the checks.

This issue was transformed by using the Coccinelle software.
