offsetof(struct ..., link_caps[dev_count]) uses a non-constant array index; this is not valid with standard offsetof/__builtin_offsetof and can fail to compile. Compute the size as sizeof(*caps) + dev_count * sizeof(caps->link_caps[0]) (or the equivalent using the element type) instead.

Suggested change
size_t caps_size = offsetof(struct ipc4_uaol_capabilities, link_caps[dev_count]);
size_t caps_size = sizeof(*caps) + dev_count * sizeof(caps->link_caps[0]);

gtw_cfg_szie is very likely a misspelled identifier (expected something like gtw_cfg_size). As written, this will fail to compile unless that exact symbol exists. Rename it to the correct size variable used for the gateway config blob length.

hchan is derived as channels_count - 1. If channels_count is 0, this underflows and encodes an invalid hchan value. Clamp or validate the channel count before subtracting (e.g., ensure the minimum encoded value is 0 and only subtract when channels_count > 0).
