Clang-16 produces this warning, which is fatal with CONFIG_WERROR: ../drivers/media/radio/wl128x/fmdrv_common.c:1237:19: error: variable 'cmd_cnt' set but not used [-Werror,-Wunused-but-set-variable] int ret, fw_len, cmd_cnt; ^ 1 error generated. What happens is that cmd_cnt tracks the amount of firmware data packets were transfered, which is printed only when debug is used. Switch to use the firmware count, as the message is all about reporting a partial firmware transfer.

The tc358746 driver selects CONFIG_GENERIC_PHY_MIPI_DPHY and links to that, but this fails when CONFIG_GENERIC_PHY is disabled, because Kbuild then never enters the drivers/phy directory for building object files: ERROR: modpost: "phy_mipi_dphy_get_default_config_for_hsclk" [drivers/media/i2c/tc358746.ko] undefined! Add an explicit 'select GENERIC_PHY' here to ensure that the directory is entered, and add another dependency on that symbol so make it more obvious what is going on if another driver has the same problem, as this will produce a Kconfig warning.

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues
