2021-03-28uio: uio_dfl: add userspace i/o driver for DFL busXu Yilun3-0/+84
This patch supports the DFL drivers be written in userspace. This is realized by exposing the userspace I/O device interfaces. The driver now only binds the ether group feature, which has no irq. So the irq support is not implemented yet.

2021-03-28misc/pvpanic: add PCI driverMihai Carabas3-0/+134
Add support for pvpanic PCI device added in qemu [1]. At probe time, obtain the address where to read/write pvpanic events and pass it to the generic handling code. Will follow the same logic as pvpanic MMIO device driver. At remove time, unmap base address and disable PCI device.

When device_create_file() fails and returns a non-zero value, no error return code of driver_sysfs_add() is assigned. To fix this bug, ret is assigned with the return value of device_create_file(), and then ret is checked.

2021-03-28driver core: Use unbound workqueue for deferred probesYogesh Lal1-1/+1
Deferred probe usually runs only on pinned kworkers, which might take longer time if a device contains multiple sub-devices. One such case is of sound card on mobile devices, where we have good number of mixers and controls per mixer. We observed boot up improvement - deferred probes take ~600ms when bound to little core kworker and ~200ms when deferred probe is queued on unbound wq. This is due to scheduler moving the worker running deferred probe work to big CPUs. Without this change, we see the worker is running on LITTLE CPU due to affinity. Since kworker runs deferred probe of several devices, the locality may not be important. Also, init thread executing driver initcalls, can potentially migrate as it has cpu affinity set to all cpus.In addition to this, async probes use unbounded workqueue. So, using unbounded wq for deferred probes looks to be similar to these w.r.t. scheduling behavior.

2021-03-28kgdbts: Switch to do_sys_openat2() for breakpoint testingDaniel Thompson1-18/+28
Currently kgdbts can get stuck waiting for do_sys_open() to be called in some of the current tests. This is because C compilers often automatically inline this function, which is a very thin wrapper around do_sys_openat2(), into some of its callers. gcc-10 does this on (at least) both x86 and arm64. We can fix the test suite by placing the breakpoints on do_sys_openat2() instead since that isn't (currently) inlined. However do_sys_openat2() is a static function so we cannot simply use an addressof. Since we are testing debug machinery it is acceptable to use kallsyms to lookup a suitable address because this is more or less what kdb does in the same circumstances. Re-implement lookup_addr() to be based on kallsyms rather than function pointers.

2021-03-28usb: gadget: s3c: Fix incorrect resources releasingChristophe JAILLET1-11/+3
Since commit 188db4435ac6 ("usb: gadget: s3c: use platform resources"), 'request_mem_region()' and 'ioremap()' are no more used, so they don't need to be undone in the error handling path of the probe and in the remove function. Remove these calls and the unneeded 'rsrc_start' and 'rsrc_len' global variables.

2021-03-28usb: misc: usbsevseg: update to use usb_control_msg_send()Anant Thazhemadam1-43/+17
The newer usb_control_msg_{send|recv}() API ensures that a short read is treated as an error, data can be used off the stack, and raw usb pipes need not be created in the calling functions. For this reason, instances of usb_control_msg() have been replaced with usb_control_msg_send() appropriately.

For this reason, instances of usb_control_msg() have been replaced with usb_control_msg_{recv|send}() appropriately. Now, we also test for a short device descriptor (which USB core should already have fetched if you get to probe this driver), but which wasn't verified again here before.

Many of the DT kerneldoc comments are lacking a 'Return' section. Let's add the section in cases we have a description of return values. There's still some cases where the return values are not documented.
