linux-next: build warning after merge of the drm-misc tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 819 bytes --]

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

WARNING: modpost: drivers/gpu/drm/bridge/chipone-icn6211.prelink.o(.exit.data+0x0): Section mismatch in reference from the variable __cfi_jt_cleanup_module to the function .init.text:cleanup_module()
The variable __exitdata __cfi_jt_cleanup_module references
a function __init cleanup_module().
This is often seen when error handling in the exit function
uses functionality in the init path.
The fix is often to remove the __init annotation of
cleanup_module() so it may be used outside an init section.

Introduced by commit

  8dde6f7452a1 ("drm: bridge: icn6211: Add I2C configuration support")

The chipone_exit function should not be marked __init.

That has arrived in linux-next today for the first time.  It is in the
drm tree, but that tree has had build problems for some time and so has
not been included completely until today.

I do have commit c7703ce38c1e (in fact it is in Linus' tree), but that
commit does not address the warning above.  I am still (as of Friday)
getting that warning.

Ups, had not seen this one coming.
We are in the process of removing the drivers in drivers/video/fbdev/omap2/omapfb/
and decided to introduce the new drivers early to get them out of a
longer patch series.

Should we have a config dependency to not allow the old fbdev omap
when the drm omap driver is enabled? I think that would take care of
all this.

Or too annoying for development?

Also note that fbdev is in drm-misc now, so we should be able to fix
this all without cross-tree conflicts.

Oops :-(

The new drivers were initially part of a patch series that removed the
duplicated drivers. The new drivers then got fast-tracked, and I didn't
notice this issue.

Note that drivers/video/fbdev/omap2/omapfb/ will stay, it's
drivers/gpu/drm/omapdrm/displays/ that is being removed. FB_OMAP2
already depends on DRM_OMAP = n, I propose doing something similar at
the level of the individual display drivers.

I've just posted "[PATCH 0/2] Fix module name clash with omapdrm and DRM
panel modules" that should solve this issue.
