2021-09-17clk: imx: Rework all clk_hw_register_gate wrappersAbel Vesa1-41/+23
Instead of having multiple inline functions that were calling clk_hw_register_gate, implement a generic low-level __imx_clk_hw_gate and implement the rest as macros that pass on as arguments whatever is needed in each case.

2021-09-17virtio-gpu: fix possible memory allocation failureliuyuntao1-7/+1
When kmem_cache_zalloc in virtio_gpu_get_vbuf fails, it will return an error code. But none of its callers checks this error code, and a core dump will take place. Considering many of its callers can't handle such error, I add a __GFP_NOFAIL flag when calling kmem_cache_zalloc to make sure it won't fail, and delete those unused error handlings.

2021-09-17crypto: img-hash - remove need for error return variable retColin Ian King1-6/+1
The assignment to error return variable ret and then the jump to an error exit path can be simplified by just returning the error return at the failure point. This allows variable ret and the error return path to be removed. This cleans up a static analysis warninng that variable ret is being assigned (value never being used) and being re-assigned later.

Enable the DAC early wake when then link operates at 10BaseT allows power savings in the hundreds of milli Watts by shutting down the transmitter. A number of errata have been issued for various Gigabit PHYs and the recommendation is to enable both the early and forced DAC wake to be on the safe side. This needs to be done dynamically based upon the link state, which is why a link_change_notify callback is utilized.

On BCM5301x port 8 requires a fixed link when used. Years ago when b53 was an OpenWrt downstream driver (with configuration based on sometimes bugged NVRAM) there was a need for a fixup. In case of forcing fixed link for (incorrectly specified) port 5 the code had to actually setup port 8 link. For upstream b53 driver with setup based on DT there is no need for that workaround. In DT we have and require correct ports setup.

2021-09-17pinctrl: qcom: spmi-gpio: correct parent irqspec translationDavid Collins1-3/+34
pmic_gpio_child_to_parent_hwirq() and gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl- spmi-gpio irqspec to an SPMI controller irqspec. When they do this, they use a fixed SPMI slave ID of 0 and a fixed GPIO peripheral offset of 0xC0 (corresponding to SPMI address 0xC000). This translation results in an incorrect irqspec for secondary PMICs that don't have a slave ID of 0 as well as for PMIC chips which have GPIO peripherals located at a base address other than 0xC000. Correct this issue by passing the slave ID of the pinctrl-spmi- gpio device's parent in the SPMI controller irqspec and by calculating the peripheral ID base from the device tree 'reg' property of the pinctrl-spmi-gpio device.

2021-09-16hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfsVadim Pasternak1-3/+9
Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature. Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum. Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS.

2021-09-16net: 6pack: Fix tx timeout and slot timeGuenter Roeck1-2/+2
tx timeout and slot time are currently specified in units of HZ. On Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this results in the following error message. drivers/net/hamradio/6pack.c: In function 'sixpack_open': drivers/net/hamradio/6pack.c:71:41: error: unsigned conversion from 'int' to 'unsigned char' changes value from '256' to '0' In the 6PACK protocol, tx timeout is specified in units of 10 ms and transmitted over the wire: https://www.linux-ax25.org/wiki/6PACK Defining a value dependent on HZ doesn't really make sense, and presumably comes from the (very historical) situation where HZ was originally 100. Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity: mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100); and the SIXP_TXDELAY walue is sent as a byte over the wire.

2021-09-163com 3c515: make it compile on 64-bit architecturesLinus Torvalds1-1/+1
This driver isn't enabled most places because of the ISA config dependency, but alpha still has it. And I think the 'Jensen' actually did have an ISA slot. However, it doesn't build cleanly, because the "Vortex bus master" code just casts the skb->data pointer to 'int': outl((int) (skb->data), ioaddr + Wn7_MasterAddr); which is all kinds of broken. Even on a good old traditional PC/AT it would be broken because the high bits will be random kernel address bits, but presumably the hardware ignores those bits. I mean, it's ISA. We're talking 16MB dma limits. The "good old days". Make the build happy with this kind of craziness by using the proper isa_virt_to_bus() handling that the full bus master code uses anyway (the Vortex bus mastering is a limited special case). Who knows, this might even work. Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
