Commit 6c393ebbd74a ("ASoC: SOF: core: Implement IPC version fallback if firmware files are missing") changed the order of some operations and the firmware paths are not available anymore at snd_sof_probe() time.
Precisely, fw_filename_prefix is set by sof_select_ipc_and_paths() via
plat_data->fw_filename_prefix = out_profile.fw_path;
but sof_init_environment() which calls this function was moved from snd_sof_device_probe() to sof_probe_continue(). Moreover, snd_sof_probe() was moved from sof_probe_continue() to sof_init_environment(), but before the call to sof_select_ipc_and_paths().
The problem here is that amd_sof_acp_probe() uses fw_filename_prefix to compute fw_code_bin and fw_data_bin paths, and because the field is not yet initialized, the paths end up containing (null):
snd_sof_amd_vangogh 0000:04:00.5: Direct firmware load for (null)/sof-vangogh-code.bin failed with error -2 snd_sof_amd_vangogh 0000:04:00.5: sof signed firmware code bin is missing snd_sof_amd_vangogh 0000:04:00.5: error: failed to load DSP firmware -2 snd_sof_amd_vangogh: probe of 0000:04:00.5 failed with error -2
Move usage of fw_filename_prefix right before request_firmware() calls in acp_sof_load_signed_firmware().

File path already saved in adata->fw_code_bin in amd_sof_acp_probe function. No need to get it again.
As already stated in the patch description, fw_filename_prefix is not available anymore when amd_sof_acp_probe() gets invoked, and that is the root cause of ending up with (null) in the computed file path.
Hence, the patch ensures amd_sof_acp_probe() computes the file name, without prefix, while acp_sof_load_signed_firmware() adds the prefix.
