Subject: [PATCH] drm/omap: Remove aggregate initialization of new_mode in omap_connector_mode_valid
Date: Mon, 22 Jun 2020 18:36:10 -0700	[thread overview]
Message-ID: <> (raw)

After commit 42acb06b01b1 ("drm: pahole struct drm_display_mode"), clang

drivers/gpu/drm/omapdrm/omap_connector.c:92:39: warning: braces around
scalar initializer [-Wbraced-scalar-init]
        struct drm_display_mode new_mode = { { 0 } };
1 warning generated.

After the struct was shuffled, the second set of braces is no longer
needed because we are not initializing a structure (struct list_head)
but a regular integer (int clock).

However, looking into it further, this initialization is pointless
because new_mode is used as the destination of drm_mode_copy, where the
members of new_mode will just be completely overwritten with the members
of mode. Just remove the initialization of new_mode so that there is no
more warning and we don't need to worry about updating the
initialization if the structure ever get shuffled again.
