Subject: [PATCH 1/8] staging: media: atomisp: initialize settings to 0
Date: Wed, 24 May 2023 14:11:43 +0200	[thread overview]
Message-ID: <20230524121150.435736-2-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20230524121150.435736-1-hverkuil-cisco@xs4all.nl>

Fix a compiler warning:

drivers/staging/media/atomisp/pci/atomisp_gmin_platform.c:1525:13: warning: 'settings' may be used uninitialized [-Wmaybe-uninitialized]

The 'settings' variable is actually always initialized, but the
compiler isn't quite able to figure that out. Just initialize it
to 0 to avoid this warning.
