Merge tag 'char-misc-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char / misc driver updates from Greg KH: "Here is the big char/misc driver update for 5.11-rc1. Continuing the tradition of previous -rc1 pulls, there seems to be more and more tiny driver subsystems flowing through this tree. Lots of different things, all of which have been in linux-next for a while with no reported issues: - extcon driver updates - habannalab driver updates - mei driver updates - uio driver updates - binder fixes and features added - soundwire driver updates - mhi bus driver updates - phy driver updates - coresight driver updates - fpga driver updates - speakup driver updates - slimbus driver updates - various small char and misc driver updates" * tag 'char-misc-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (305 commits) extcon: max77693: Fix modalias string extcon: fsa9480: Support TI TSU6111 variant extcon: fsa9480: Rewrite bindings in YAML and extend dt-bindings: extcon: add binding for TUSB320 extcon: Add driver for TI TUSB320 slimbus: qcom: fix potential NULL dereference in qcom_slim_prg_slew() siox: Make remove callback return void siox: Use bus_type functions for probe, remove and shutdown spmi: Add driver shutdown support spmi: fix some coding style issues at the spmi core spmi: get rid of a warning when built with W=1 uio: uio_hv_generic: use devm_kzalloc() for private data alloc uio: uio_fsl_elbc_gpcm: use device-managed allocators uio: uio_aec: use devm_kzalloc() for uio_info object uio: uio_cif: use devm_kzalloc() for uio_info object uio: uio_netx: use devm_kzalloc() for or uio_info object uio: uio_mf624: use devm_kzalloc() for uio_info object uio: uio_sercos3: use device-managed functions for simple allocs uio: uio_dmem_genirq: finalize conversion of probe to devm_ handlers uio: uio_dmem_genirq: convert simple allocations to device-managed ...
