2021-04-19spi: stm32-qspi: fix pm_runtime usage_count counterChristophe Kerello
pm_runtime usage_count counter is not well managed. pm_runtime_put_autosuspend callback drops the usage_counter but this one has never been increased. Add pm_runtime_get_sync callback to bump up the usage counter. It is also needed to use pm_runtime_force_suspend and pm_runtime_force_resume APIs to handle properly the clock.

2021-04-19platform/x86: intel_pmc_core: Handle sub-states genericallyGayatri Kammela
The current implementation of pmc_core_substate_res_show() is written specifically for Tiger Lake. However, new platform will also have sub-states and may support different modes. Therefore rewrite the code to handle sub-states generically. Obtain the number and type of enabled states form the PMC. Use the Low Power Mode (LPM) priority register to store the states in order from shallowest to deepest for displays. Add a for_each macro to simplify this. While changing the sub-state display it makes sense to show only the "enabled" sub-states instead of showing all possible ones.

2021-04-19platform/x86: intel_pmc_core: Remove global struct pmc_devDavid E. Box
The intel_pmc_core driver did not always bind to a device which meant it lacked a struct device that could be used to maintain driver data. So a global instance of struct pmc_dev was used for this purpose and functions accessed this directly. Since the driver now binds to an ACPI device, remove the global pmc_dev in favor of one that is allocated during probe. Modify users of the global to obtain the object by argument instead.

In probe, after calling dmi_check_system(), pass pmc_dev to a function that will handle each quirk if its variable condition is met. This allows removing the global pmc_dev later.

alignment in block mode Since commit e085b51c74cc ("mmc: meson-gx: check for scatterlist size alignment in block mode"), support for SDIO SD_IO_RW_EXTENDED transferts are properly filtered but some driver like brcmfmac still gives a block sg buffer size not aligned with SDIO block, triggerring a WARN_ONCE() with scary stacktrace even if the transfer works fine but with possible degraded performances. Simply replace with dev_warn_once() to inform user this should be fixed to avoid degraded performance. This should be ultimately fixed in brcmfmac, but since it's only a performance issue the warning should be removed.

2021-04-18rsi: fix comment syntax in file headersAditya Srivastava
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are some files in drivers/net/wireless/rsi which follow this syntax in their file headers, i.e. start with '/**' like comments, which causes unexpected warnings from kernel-doc. E.g., running scripts/kernel-doc -none on drivers/net/wireless/rsi/rsi_coex.h causes this warning: "warning: wrong kernel-doc identifier on line: * Copyright (c) 2018 Redpine Signals Inc." Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e., "/*", to prevent kernel-doc from parsing it.

into drm-fixes vmwgfx fixes for regressions in 5.12 Here's a set of 3 patches fixing ugly regressions in the vmwgfx driver. We broke lock initialization code and ended up using spinlocks before initialization breaking lockdep. Also there was a bit of a fallout from drm changes which made the core validate that unreferenced buffers have been unpinned. vmwgfx pinning code predates a lot of the core drm and wasn't written to account for those semantics. Fortunately changes required to fix it are not too intrusive. The changes have been validated by our internal ci.

2021-04-17r8169: keep pause settings on interface down/up cycleHeiner Kallweit
Currently, if the user changes the pause settings, the default settings will be restored after an interface down/up cycle, and also when resuming from suspend. This doesn't seem to provide the best user experience. Change this to keep user settings, and just ensure that in jumbo mode pause is disabled. Small drawback: When switching back mtu from jumbo to non-jumbo then pause remains disabled (but user can enable it using ethtool). I think that's a not too common scenario and acceptable.

2021-04-17airo: work around stack usage warningArnd Bergmann
gcc-11 with KASAN on 32-bit arm produces a warning about a function that needs a lot of stack space: drivers/net/wireless/cisco/airo.c: In function 'setup_card.constprop': drivers/net/wireless/cisco/airo.c:3960:1: error: the frame size of 1512 bytes is larger than 1400 bytes [-Werror=frame-larger-than=] Most of this is from a single large structure that could be dynamically allocated or moved into the per-device structure. However, as the callers all seem to have a fairly well bounded call chain, the easiest change is to pull out the part of the function that needs the large variables into a separate function and mark that as noinline_for_stack. This does not reduce the total stack usage, but it gets rid of the warning and requires minimal changes otherwise.

If the loop fails, the "while(trials--) {" loop will exit with "trials" set to -1. The test for that expects it to end with "trials" set to 0 so the warning message will not be printed. Fix this by changing from a post-op to a pre-op. This does mean that we only make 99 attempts instead of 100 but that's okay.

2021-04-17wilc1000: Bring MAC address setting in line with typical Linux behaviorDavid Mosberger-Tang
Linux network drivers normally disallow changing the MAC address when the interface is up. This driver has been different in that it allows to change the MAC address *only* when it's up. This patch brings wilc1000 behavior more in line with other network drivers. We could have replaced wilc_set_mac_addr() with eth_mac_addr() but that would break existing documentation on how to change the MAC address. Likewise, return -EADDRNOTAVAIL (not -EINVAL) when the specified MAC address is invalid or unavailable.
