firmware: arm_scmi: Fix device node validation for mailbox transport

2023-04-05T09:15:42Z

commit 2ab4f4018cb6b8010ca5002c3bdc37783b5d28c2 upstream. When mailboxes are used as a transport it is possible to setup the SCMI transport layer, depending on the underlying channels configuration, to use one or two mailboxes, associated, respectively, to one or two, distinct, shared memory areas: any other combination should be treated as invalid. Add more strict checking of SCMI mailbox transport device node descriptors.

usb: host: ohci-pxa27x: Fix and & vs | typo

2023-04-05T09:15:42Z

commit 0709831a50d31b3caf2237e8d7fe89e15b0d919d upstream. The code is supposed to clear the RH_A_NPS and RH_A_PSM bits, but it's a no-op because of the & vs | typo. This bug predates git and it was only discovered using static analysis so it must not affect too many people in real life.

drm/etnaviv: fix reference leak when mmaping imported buffer

2023-04-05T09:15:42Z

commit 963b2e8c428f79489ceeb058e8314554ec9cbe6f upstream. drm_gem_prime_mmap() takes a reference on the GEM object, but before that drm_gem_mmap_obj() already takes a reference, which will be leaked as only one reference is dropped when the mapping is closed. Drop the extra reference when dma_buf_mmap() succeeds. Cc: stable@vger.kernel.org Signed-off-by: Lucas Stach Reviewed-by: Christian Gmeiner Signed-off-by: Greg Kroah-Hartman

pinctrl: at91-pio4: fix domain name assignment

2023-04-05T09:15:41Z

commit 7bb97e360acdd38b68ad0a1defb89c6e89c85596 upstream. Since commit d59f6617eef0 ("genirq: Allow fwnode to carry name information only") an IRQ domain is always given a name during allocation (e.g. used for the debugfs entry). Drop the no longer valid name assignment, which would lead to an attempt to free a string constant when removing the domain on late probe failures (e.g. probe deferral).

xen/netback: don't do grant copy across page boundary

2023-04-05T09:15:41Z

commit 05310f31ca74673a96567fb14637b7d5d6c82ea5 upstream. Fix xenvif_get_requests() not to do grant copy operations across local page boundaries. This requires to double the maximum number of copy operations per queue, as each copy could now be split into 2. Make sure that struct xenvif_tx_cb doesn't grow too large.

Input: focaltech - use explicitly signed char type

2023-04-05T09:15:41Z

commit 8980f190947ba29f23110408e712444884b74251 upstream. The recent change of -funsigned-char causes additions of negative numbers to become additions of large positive numbers, leading to wrong calculations of mouse movement. Change these casts to be explicitly signed, to take into account negative offsets. Fixes: 3bc753c06dd0 ("kbuild: treat char as always unsigned") Signed-off-by: Jason A.

Input: alps - fix compatibility with -funsigned-char

2023-04-05T09:15:41Z

commit 754ff5060daf5a1cf4474eff9b4edeb6c17ef7ab upstream. The AlpsPS/2 code previously relied on the assumption that `char` is a signed type, which was true on x86 platforms (the only place where this driver is used) before kernel 6.2. However, on 6.2 and later, this assumption is broken due to the introduction of -funsigned-char as a new global compiler flag. Fix this by explicitly specifying the signedness of `char` when sign extending the values received from the device.
