Applied "spi: Fix unregistration of controller with fixed SPI bus number" to the regulator tree

by Mark Brown

The patch spi: Fix unregistration of controller with fixed SPI bus number has been applied to the regulator tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH] mtd: rawnand: fsl_ifc: Fix nand waitfunc return value

As per the IFC hardware manual, Most significant 2 bytes in nand_fsr register are the outcome of NAND READ STATUS command.

[PATCH][v2] mtd: rawnand: fsl_ifc: Fix eccstat array overflow for IFC ver >= 2.0.0

by Jagdish Gediya

Number of ECC status registers i.e. (ECCSTATx) has been increased in IFC version 2.0.0 due to increase in SRAM size. This is causing eccstat array to over flow. So, replace eccstat array with u32 variable to make it fail-safe and independent of number of ECC status registers or SRAM size.

[PATCH] PCI / PM: Always check PME wakeup capability for runtime wakeup support

by Kai-Heng Feng

USB controller ASM1042 stops working after commit de3ef1eb1cd0 ("PM / core: Drop run_wake flag from struct dev_pm_info"). The device in question is not power managed by platform firmware, furthermore, it only supports PME# from D3cold: Capabilities: [78] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Before the commit, the device never gets runtime suspended. After the commit, the device gets runtime suspended, so it does not respond to any PME#. usb_hcd_pci_probe() mandatorily calls device_wakeup_enable(), hence device_can_wakeup() in pci_dev_run_wake() always returns true. So pci_dev_run_wake() needs to check PME wakeup capability as its first condition.
