2020-12-02i2c: imx: Don't generate STOP condition if arbitration has been lostChristian Eggers
If arbitration is lost, the master automatically changes to slave mode. I2SR_IBB may or may not be reset by hardware. Raising a STOP condition by resetting I2CR_MSTA has no effect and will not clear I2SR_IBB. So calling i2c_imx_bus_busy() is not required and would busy-wait until timeout.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "I'm sad to say that we've got an unusually large arm64 fixes pull for rc7 which addresses numerous significant instrumentation issues with our entry code. Without these patches, lockdep is hopelessly unreliable in some configurations [1,2] and syzkaller is therefore not a lot of use because it's so noisy. Although much of this has always been broken, it appears to have been exposed more readily by other changes such as 044d0d6de9f5 ("lockdep: Only trace IRQ edges") and general lockdep improvements around IRQ tracing and NMIs. Fixing this properly required moving much of the instrumentation hooks from our entry assembly into C, which Mark has been working on for the last few weeks. We're not quite ready to move to the recently added generic functions yet, but the code here has been deliberately written to mimic that closely so we can look at cleaning things up once we have a bit more breathing room. Having said all that, the second version of these patches was posted last week and I pushed it into our CI (kernelci and cki) along with a commit which forced on PROVE_LOCKING, NOHZ_FULL and CONTEXT_TRACKING_FORCE.

2020-12-02s390: fix irq state tracingHeiko Carstens
With commit 58c644ba512c ("sched/idle: Fix arch_cpu_idle() vs tracing") common code calls arch_cpu_idle() with a lockdep state that tells irqs are on. This doesn't work very well for s390: psw_idle() will enable interrupts to wait for an interrupt. As soon as an interrupt occurs the interrupt handler will verify if the old context was psw_idle(). If that is the case the interrupt enablement bits in the old program status word will be cleared. A subsequent test in both the external as well as the io interrupt handler checks if in the old context interrupts were enabled. Due to the above patching of the old program status word it is assumed the old context had interrupts disabled, and therefore a call to TRACE_IRQS_OFF (aka trace_hardirqs_off_caller) is skipped. Which in turn makes lockdep incorrectly "think" that interrupts are enabled within the interrupt handler. Fix this by unconditionally calling TRACE_IRQS_OFF when entering interrupt handlers. Also call unconditionally TRACE_IRQS_ON when leaving interrupts handlers. This leaves the special psw_idle() case, which now returns with interrupts disabled, but has an "irqs on" lockdep state. So callers of psw_idle() must adjust the state on their own, if required. This is currently only __udelay_disabled().

2020-12-02media: rdacm20: Enable GPIO1 explicitlyJacopo Mondi
The MAX9271 GPIO1 line that controls the sensor reset is by default enabled after a serializer chip reset. As rdacm20 does not go through an explicit serializer reset, make sure GPIO1 is enabled to make the camera module driver more robust.

2020-12-02media: v4l: subdev: Set sd->devnode before registering the subdevSakari Ailus
The subdev's video device node was only assigned after registering the device node in the system. While it is unlikely that a driver needed to use this field in handling system calls to its file handle, there remains a slim chance the devnode field remains NULL while the driver expects to find a video node there. Assign the devnode field before registering the device, and assign it back to NULL if the registration failed.

2020-12-02media: ccs: Request for "reset" GPIOSakari Ailus
The DT bindings documented "reset-gpios" property but the driver never made use of it. Instead it used a GPIO called "xshutdown", with apprently wrong polarity. Fix this by requesting "reset" GPIO with the right polarity first, and if that fails, then request "xshutdown" GPIO with the old polarity. This way it works for new users as expected while if someone, somewhere, depended on "xshutdown" GPIO, that continues to work as well.
