This is a followup on 44117a1d1732 ("serial: core: mark port as initialized after successful IRQ change"). Nikola has been using autoconfig via setserial and reported a crash similar to what I fixed in the earlier mentioned commit. Here I do the same fixup for the autoconfig. I wasn't sure that this is the right approach. Nikola confirmed that it fixes his crash.

Normal 512-byte get/set of a TLV isn't supported but we were registering the normal get/set anyway and relying on omitting the SNDRV_CTL_ELEM_ACCESS_[READ|WRITE] flags to prevent them being called. Trouble is if this gets broken in the core ALSA code - as it has been since at least 4.14 - the standard get/set can be called unexpectedly and corrupt memory. There's no point providing functions that won't be called and it's a trivial change. The benefit is that if the ALSA core gets broken again we get a big fat immediate NULL dereference instead of a memory corruption timebomb.

When a USB device gets plugged on ASUS PRIME B350M-A's front ports, the xHC stops working: [ 549.114587] xhci_hcd 0000:02:00.0: WARN: xHC CMD_RUN timeout [ 549.114608] suspend_common(): xhci_pci_suspend+0x0/0xc0 returns -110 [ 549.114638] xhci_hcd 0000:02:00.0: can't suspend (hcd_pci_runtime_suspend returned -110) Delay before running xHC command CMD_RUN can workaround the issue. Use a new quirk to make the delay only targets to the affected xHC.
