Subject[PATCH 5.0 078/115] i3c: dw: Fix dw_i3c_master_disable controller by using correct mask
Date
From: Vitor Soares <vitor.soares@synopsys.com>

commit 907621e94d49b85cd76f13110eceb940a182c69e upstream.

The controller was being disabled incorrectly. The correct way is to clear
the DEV_CTRL_ENABLE bit.

Fix this by clearing this bit.
