The `rtl8188eu` driver is built as a kmod in order to avoid symbol conflicts (at link-time) with other Realtek drivers. Internally, we use this driver as builtin [vs kmod], and we've identified the `efuse_power_switch()` symbol to be conflicting at link-time with the one from the `rtlwifi` driver. An alternative solution would have been to rename the function, but it doesn't look like it's being used outside of this driver, so just make it static. Signed-off-by:

Since wfx_tx_get_raw_link_id() return an unsigned, it makes no sense to return a negative value. "15" is a better value since it is used by firmware for stations that have not yet associated link-ids. Note that this should never happens since driver set max_ap_assoc_sta to 14.

Merge tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of IIO new device support, cleanups and features for the 5.5 cycle Third version with the adis rework set dropped as better to just have a fresh version of that at some future date. The usual mixed backs of new device support being added to drivers, long term reworks continuing and little per driver cleanups and features. Also a few trivial counter subsystem tidy ups on behalf of William. Core new feature * Device label support. A long requested feature no one got around to implementing before. Allows DT based provision of a 'label' that identifies a device uniquely within a system. This differs from existing 'name' which is meant to be the part number. New device support * ingenic-adc - Support for the JZ4770 SoC ADC including bindings. * inv_mpu6050 - Add support for magnetometer in MPU925x parts. Fiddly to do as this is actually a separate device sitting inside the package, but with the master device being able to schedule reads etc. Will only run if the auxiliary bus is not in use for any other devices. Features * ad7192 - Userspace calibration controls to do zero and full scale. * st_lsm6dsx - Enable latched interrupts by default for sensors events with related clear. - Motion events and related wakeup source. This needed quite a bit of refactoring as well. Cleanups and minor features * ad7192 - sysfs ABI docs * ad7949 - Remove code to readback configuration word as driver never actually enabled it. - Fix incorrect xfer length. Not actually known to cause problems other than wasted bus usage. * adis16080 - Replace core mlock usage with local lock with more appropriate scope. * adis16130 - Remove pointless mlock usage. * adis16240 - Remove include of gpio.h as no gpio usage. * atlas-ph-sensor - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * bh1750 - Fix up a static compiler warning and make the code more readable. - yaml conversion of binding + MAINTAINERS entry. * bmp280 - Drop a stray newline. * cm36651 - Drop a redundant assignment * itg3200 - Alignment cleanup. * max31856 - Add missing of_node and parent references, useful to identify the device. * sc27xx_adc - Use devm_hwspin_lock_request_specific rather than local rolled version. * stm32-lptimer counter - kernel-doc warning. * stm32-timer counter - kernel-doc warning. - Alignment cleanup. * sx9500 - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * tcs3414 - Improve logical ordering of buffer predisable / postenable functions.

Alexandru Ardelean authored
The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. The position of iio_triggered_buffer_postenable() is correct. Note this is not stable material. It's a fix in the logical model rather fixing an actual bug. These are being tidied up throughout the subsystem to allow more substantial rework that was blocked by variations in how things were done.

There is no loop. So, it must be looping in the caller tracing_read_pipe() via the "waitagain" label. Crashdump analyze uncovered that iter->seq was completely zeroed at this point, including iter->seq.seq.size. It means that print_trace_line() was never able to print anything and there was no forward progress. The culprit seems to be in the code: /* reset all but tr, trace, and overruns */ memset(&iter->seq, 0, sizeof(struct trace_iterator) - offsetof(struct trace_iterator, seq)); It was added by the commit 53d0aa77 ("ftrace: add logic to record overruns"). It was v2.6.27-rc1. It was the time when iter->seq looked like: struct trace_seq { unsigned char buffer[PAGE_SIZE]; unsigned int len; }; There was no "size" variable and zeroing was perfectly fine. The solution is to reinitialize the structure after or without zeroing. Link: http://lkml.kernel.org/r/20191011142134.11997-1-pmladek@suse.comSigned-off-by:
