ASoC: SOF: amd: Compute file paths on firmware load
[ Upstream commit d9cacc1a2af2e1cd781b5cd2a3e57fbde64f5a2d ]
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().
