  rpmsg: virtio: fix error handling in TX buffer wait (2026-10-14 09:45:47 -0600)

----------------------------------------------------------------
rpmsg updates for v7.4

Allow virtio rpmsg to use separate transmit and receive buffer counts
based on the vring sizes, and obtain buffer sizes from virtio config
space when the feature is negotiated. Document the configuration and
report the MTU in the sample driver.

Fix signal interruption and timeout handling while waiting for a virtio
transmit buffer. Release the device tree node reference on MediaTek
channel teardown.

Convert the rpmsg control ioctl comments to kernel-doc format.
