+Subject: media: rc: compile rc-cec.c into rc-core
+
+From: Hans Verkuil <hverkuil@xs4all.nl>
+
+commit f09f9f93afad770a04b35235a0aa465fcc8d6e3d upstream.
+
+The rc-cec keymap is unusual in that it can't be built as a module,
+instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC
+is set. This is because it can be called from drm_dp_cec_set_edid() via
+cec_register_adapter() in an asynchronous context, and it is not
+allowed to use request_module() to load rc-cec.ko in that case. Trying to
+do so results in a 'WARN_ON_ONCE(wait && current_is_async())'.
+
+Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we
+just compile this keymap into the rc-core module and never as a
+separate module.

+Subject: media: usbtv: Fix deadlock on suspend
+
+From: Maxim Mikityanskiy <maxtram95@gmail.com>
+
+commit 8a7e27fd5cd696ba564a3f62cedef7269cfd0723 upstream.
+
+usbtv doesn't support power management, so on system suspend the
+.disconnect callback of the driver is called. The teardown sequence
+includes a call to snd_card_free. Its implementation waits until the
+refcount of the sound card device drops to zero, however, if its file is
+open, snd_card_file_add takes a reference, which can't be dropped during
+the suspend, because the userspace processes are already frozen at this
+point. snd_card_free waits for completion forever, leading to a hang on
+suspend.
+
+This commit fixes this deadlock condition by replacing snd_card_free
+with snd_card_free_when_closed, that doesn't wait until all references
+are released, allowing suspend to progress.

+Subject: sh_eth: fix TRSCER mask for R7S9210
+
+From: Sergey Shtylyov <s.shtylyov@omprussia.ru>
+
+commit 165bc5a4f30eee4735845aa7dbd6b738643f2603 upstream.
+
+According to the RZ/A2M Group User's Manual: Hardware, Rev. 2.00,
+the TRSCER register has bit 9 reserved, hence we can't use the driver's
+default TRSCER mask. Add the explicit initializer for sh_eth_cpu_data::
+trscer_err_mask for R7S9210.
