-Subject: [PATCH] [media] media: rc: add sysfs scancode filtering interface
-
-Add and document a generic sysfs based scancode filtering interface for
-making use of IR data matching hardware to filter out uninteresting
-scancodes. Two filters exist, one for normal operation and one for
-filtering scancodes which are permitted to wake the system from suspend.
-
-The following files are added to /sys/class/rc/rc?/:
- - filter: normal scancode filter value
- - filter_mask: normal scancode filter mask
- - wakeup_filter: wakeup scancode filter value
- - wakeup_filter_mask: wakeup scancode filter mask
-
-A new s_filter() driver callback is added which must arrange for the
-specified filter to be applied at the right time. Drivers can convert
-the scancode filter into a raw IR data filter, which can be applied
-immediately or later (for wake up filters).

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Propagate errors returned by drivers from the s_filter callback back to
-userland when updating scancode filters. This allows userland to see
-when the filter couldn't be updated, usually because it's not a valid
-filter for the hardware.
-
-Previously the filter was being updated conditionally on success of
-s_filter, but the write always reported success back to userland.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add generic scancode filtering of RC input events, and fall back to
-permitting any RC_FILTER_NORMAL scancode filter to be set if no s_filter
-callback exists. This allows raw IR decoder events to be filtered, and
-potentially allows hardware decoders to set looser filters and rely on
-generic code to filter out the corner cases.

-Subject: [PATCH] [media] rc: add allowed/enabled wakeup protocol masks
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Only a single allowed and enabled protocol mask currently exists in
-struct rc_dev, however to support a separate wakeup filter protocol two
-of each are needed, ideally as an array.
-
-Therefore make both rc_dev::allowed_protos and rc_dev::enabled_protocols
-arrays, update all users to reference the first element
-(RC_FILTER_NORMAL), and add a couple more helper functions for drivers
-to use for setting the allowed and enabled wakeup protocols.
-
-We also rename allowed_protos to allowed_protocols while we're at it,
-which is more consistent with enabled_protocols.

-Subject: [PATCH] [media] rc-main: automatically refresh filter on protocol
- change
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-When either of the normal or wakeup filter protocols are changed,
-refresh the corresponding scancode filter, i.e. try and set the same
-scancode filter with the new protocol. If that fails clear the filter
-instead.
-
-If no protocol was selected the filter is just cleared, and if no
-s_filter callback exists the filter is left unmodified.
-
-Similarly clear the filter mask when the filter is set if no protocol is
-currently selected.
-
-This simplifies driver code which no longer has to explicitly worry
-about modifying the filter on a protocol change. This also allows the
-change_wakeup_protocol callback to be omitted entirely if there is only
-a single available wakeup protocol at a time, since selecting no
-protocol will automatically clear the wakeup filter, disabling wakeup.

-
-While playing with make coccicheck I noticed this message:
-drivers/media/rc/rc-main.c:1245:3-9: preceding lock on line 1238
-
-It was introduced by commit 587d1b06e07b ([media] rc-core: reuse device
-numbers) which returns -ENOMEM after a mutex_lock without first
-unlocking it when there are no more device numbers left. The added code
-doesn't depend on the device lock, so move it before the lock is taken.
