Hi ARM SoC Team, Please pull ! Regards, Sudeep -->8 The following changes since commit 9abf2313adc1ca1b6180c508c25f22f9395cc780: Linux 6.1-rc1 (2022-10-16 15:36:24 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-fixes-6.1 for you to fetch changes up to 1eff6929aff594fba3182660f7b6213ec0ceda0c: firmware: arm_scmi: Fix deferred_tx_wq release on error paths (2022-11-01 11:36:20 +0000) ---------------------------------------------------------------- Arm SCMI fixes for v6.1 A bunch of fixes to handle: 1. A possible resource leak in scmi_remove(). The returned error value gets ignored by the driver core and can remove the device and free the devm-allocated resources. As a simple solution to be able to easily backport, the bind attributes in the driver is suppressed as there is no need to support it. Additionally the remove path is cleaned up by adding device links between the core and the protocol devices so that a proper and complete unbinding happens. 2. A possible spin-loop in the SCMI transmit path in case of misbehaving platform firmware. A timeout is added to the existing loop so that the SCMI stack can bailout aborting the transmission with warnings. 3. Optional Rx channel correctly by reporting any memory errors instead of ignoring the same with other allowed errors. 4. The use of proper device for all the device managed allocations in the virtio transport. 5. Incorrect deferred_tx_wq release on the error paths by using devres API(devm_add_action_or_reset) to manage the release in the error path. ---------------------------------------------------------------- Cristian Marussi (6): firmware: arm_scmi: Cleanup the core driver removal callback firmware: arm_scmi: Suppress the driver's bind attributes firmware: arm_scmi: Make tx_prepare time out eventually firmware: arm_scmi: Make Rx chan_setup fail on memory errors firmware: arm_scmi: Fix devres allocation device in virtio transport firmware: arm_scmi: Fix deferred_tx_wq release on error paths drivers/firmware/arm_scmi/bus.c | 11 ++++++++++ drivers/firmware/arm_scmi/common.h | 5 ++++- drivers/firmware/arm_scmi/driver.c | 41 ++++++++++++++++++++++++------------- drivers/firmware/arm_scmi/mailbox.c | 2 +- drivers/firmware/arm_scmi/optee.c | 2 +- drivers/firmware/arm_scmi/shmem.c | 31 ++++++++++++++++++++++++---- drivers/firmware/arm_scmi/smc.c | 2 +- drivers/firmware/arm_scmi/virtio.c | 26 ++++++++++++++--------- 8 files changed, 88 insertions(+), 32 deletions(-)
