Subject: [PATCH] HID: amd_sfh: Use amd_sfh_clear_intr(mp2) call only once in
 sfh_init_work()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 18 Sep 2024 13:11:00 +0200

A amd_sfh_clear_intr(mp2) call was immediately used after a return code
check for a amd_sfh_hid_client_init() call in this function implementation.
Thus use such a function call only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
