linux-toradex.git/include/media, branch v3.0-rc3 Linux kernel for Apalis and Colibri modules [media] v4l: Fix media_entity_to_video_device macro argument name 2011-06-01T12:42:03+00:00 Laurent Pinchart laurent.pinchart@ideasonboard.com 2011-05-02T19:21:03+00:00 6e3ea0e711b1c4dca3c4f87ef0ab5c896c940c81 The name 'entity' is used twice in the macro body, once as the macro argument, and once as a structure field name.

The name 'entity' is used twice in the macro body, once as the macro
argument, and once as a structure field name. This breaks compilation if
the macro is called with its argument not named 'entity'.

Fix this by renaming the macro argument '__e'. This should avoid
namespace clashes.

When device_add is called in rc_register_device, the rc sysfs nodes show
up, and there's a window in which ir-keytable can be launched via udev
and trigger a show_protocols call, which runs without various rc_dev
fields filled in yet. Add some locking around registration and
store/show_protocols to prevent that from happening.
