I'm a user of the third-party kernel for the OnePlus 8T, and I'd like to request a feature for the upcoming new version. I'd like to propose the removal of kernel verification. Currently, the kernel verification process adds an extra layer of security, but it limits the ability to customize the kernel for advanced users like myself.I believe that removing this verification step would greatly benefit the community by allowing us to explore more advanced customization options while understanding the potential security implications. Please consider this request for the next version of the kernel.Thank you for your hard work on this project, and I appreciate your consideration of this feature request.

scsi: target: core: Fix deadlock due to recursive locking
e5ccce2 
[ Upstream commit a154f5f643c6ecddd44847217a7a3845b4350003 ]

The following call trace shows a deadlock issue due to recursive locking of
mutex "device_mutex". First lock acquire is in target_for_each_device() and
second in target_free_device().

oplus: Fix duplicate registration of /proc/ftm_tfa98xx

Multiple tfa chips does exist on one device, we shouldn't create it
every time on drivers probe. Make it only run once to fix the kernel
warning.

Multiple tfa chips does exist on one device, we shouldn't create it
every time on drivers probe. Make it only run once to fix the kernel

oplus: Fix duplicate registration of /proc/oplus_ke
80bcc43 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

Multiple tfa chips does exist on one device, we shouldn't create it
every time on drivers probe. Make it only run once to fix the kernel
warning.

oplus: Fix duplicate registration of /proc/oplus_ke
be813cf 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

oplus: Fix duplicate registration of /proc/oplus_ke
92d982f 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

oplus: Fix duplicate registration of /proc/oplus_ke
9eeccab 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

oplus: Fix duplicate registration of /proc/oplus_ke
08a8b4e 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

oplus: Fix duplicate registration of /proc/oplus_ke
0234a73 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

oplus: Fix duplicate registration of /proc/oplus_ke
c9041f9 
Multiple PMICs does exist on one device, which means qpnp-power-on may
get probed multiple times. It doesn't make sense to register the
directory each time when any of the PMICs get probed. Make it only run
once to fix the kernel warning.

tun: limit printing rate when illegal packet received by tun dev
68459b8 
[ Upstream commit f8bbc07ac535593139c875ffa19af924b1084540 ]

vhost_worker will call tun call backs to receive packets. If too many
illegal packets arrives, tun_do_read will keep dumping packet contents.
When console is enabled, it will costs much more cpu time to dump
packet and soft lockup will be detected.

net_ratelimit mechanism can be used to limit the dumping rate.

Multiple tfa chips does exist on one device, we shouldn't create it
every time on drivers probe. Make it only run once to fix the kernel
warning.
