io_uring: fix missing sigmask restore in io_cqring_wait()
Move get_timespec() section in io_cqring_wait() before the sigmask saving, otherwise we'll fail to restore sigmask once get_timespec() returns error.

Note it is currently minimal in that there are no events and no buffer. With care they can probably be added in additional files without messing up the clarity of what we have here. V2: Addressed some of Manuel Stahl's feedback. Fixed up kernel doc. Added more general description.

The frequency generator allows an external complex impedance to be excited with a known frequency. The response signal from the impedance is sampled by the on-board ADC and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine. The DFT algorithm returns a real (R) and imaginary (I) data-word at each output frequency. Changes since V1: Apply list review feedback: Consistently use poll_time_jiffies. Use be|le cpu endian helpers where applicable. Add various comments. Changes since V2: Fix KernelVersion tag in Documentation. Declare ad5933_default_pdata static. Fix typos.
