[ Upstream commit a574359e2e71ce16be212df3a082ed60a4bd2c5f ]
In dvb_register_frontend(), dvb_register_device() is possible to fail
but its return value is ignored.
It will cause use-after-free when module is removed, because in
dvb_unregister_frontend() it tries to unregister a not registered
device.
BUG: KASAN: use-after-free in dvb_remove_device+0x18b/0x1f0 [dvb_core]

Fix this by catching return value of dvb_register_device().
However the fe->refcount can't be put to zero immediately, because
there are still modules calling dvb_frontend_detach() when
dvb_register_frontend() fails.

There is no occurrence of the hdmi oscillator in the reference manual
(document IMX8MNRM Rev 2, 07/2022). Further, if we consider the indexes
76-81 and 134 of the "Clock Root" table of chapter 5 of the RM, there is
no entry for the source select bits 101b, which is the setting referenced
by "osc_hdmi".
Fix by renaming "osc_hdmi" with "dummy", a clock which has already been
used for missing source select bits.
Tested on the BSH SystemMaster (SMM) S2 board.

[ Upstream commit a429c60baefd95ab43a2ce7f25d5b2d7a2e431df ]
The IMX8MN platform does not have any video processing unit (VPU), and
indeed in the reference manual (document IMX8MNRM Rev 2, 07/2022) there
is no occurrence of its pll. From an analysis of the code and the RM
itself, I think vpu pll is used instead of m7 alternate pll, probably
for copy and paste of code taken from modules of similar architectures.
As an example for all, if we consider the second row of the "Clock Root"
table of chapter 5 (Clocks and Power Management) of the RM:
Clock Root offset Source Select (CCM_TARGET_ROOTn[MUX])
... ... ...
ARM_M7_CLK_ROOT 0x8080 000 - 24M_REF_CLK
001 - SYSTEM_PLL2_DIV5
010 - SYSTEM_PLL2_DIV4
011 - M7_ALT_PLL_CLK
100 - SYSTEM_PLL1_CLK
101 - AUDIO_PLL1_CLK
110 - VIDEO_PLL_CLK
111 - SYSTEM_PLL3_CLK
... ... ...
but in the source code, the imx8mn_m7_sels clocks list contains vpu_pll
for the source select bits 011b.
So, let's rename "vpu_pll" to "m7_alt_pll" to be consistent with the RM.
The IMX8MN_VPU_* constants have not been removed to ensure backward
compatibility of the patch.
No functional changes intended.

The function send_packet() has a race condition as follows:
func send_packet()
{
// do work
call usb_submit_urb()
mutex_unlock()
wait_for_event_interruptible() <-- lock gone
mutex_lock()
}
func vfd_write()
{
mutex_lock()
call send_packet() <- prev call is not completed
mutex_unlock()
}
When the mutex is unlocked and the function send_packet() waits for the
call to complete, vfd_write() can start another call, which leads to the
"URB submitted while active" warning in usb_submit_urb().
Fix this by removing the mutex_unlock() call in send_packet() and using
mutex_lock_interruptible().

It is because the error handling in vidtv_bridge_dvb_init() is wrong.
First, vidtv_bridge_dmx(dev)_init() will clean themselves when fail, but
goto fail_dmx(_dev): calls release functions again, which causes
use-after-free.
Also, in fail_fe, fail_tuner_probe and fail_demod_probe, j = i will cause
out-of-bound when i finished its loop (i == NUM_FE). And the loop
releasing is wrong, although now NUM_FE is 1 so it won't cause problem.

As can be seen in elants_i2c_power_off(), we want the reset GPIO
asserted when power is off. The reset GPIO is active low so we need
the reset line logic low when power is off to avoid leakage.
We have a problem, though, at probe time. At probe time we haven't
powered the regulators on yet but we have:
devm_gpiod_get(&client->dev, "reset", GPIOD_OUT_LOW);
While that _looks_ right, it turns out that it's not. The
GPIOD_OUT_LOW doesn't mean to init the GPIO to low. It means init the
GPIO to "not asserted". Since this is an active low GPIO that inits it
to be high.
Let's fix this to properly init the GPIO. Now after both probe and
power off the state of the GPIO is consistent (it's "asserted" or
level low).
Once we fix this, we can see that at power on time we no longer to
assert the reset GPIO as the first thing. The reset GPIO is _always_
asserted before powering on. Let's fix powering on to account for
this.

end up claiming that we support all the OPPs which is not likely to be

conflicting OPPs).

This fixes crashes in bfq_add_bfqq_busy due to waker_bfqq being NULL,
but woken_list_node still being hashed. This would happen when
bfq_init_rq() expects a brand new allocated queue to be returned from
bfq_get_bfqq_handle_split() and unconditionally updates waker_bfqq
without resetting woken_list_node. Since we can always return oom_bfqq
when attempting to allocate, we cannot assume waker_bfqq starts as NULL.
Avoid setting woken_bfqq for oom_bfqq entirely, as it's not useful.
