Subject: [PATCH 5.4 150/260] ASoC: Intel: Skylake: Fix passing loadable flag for module

From: Gustaw Lewandowski <gustaw.lewandowski@...ux.intel.com>

[ Upstream commit c5ed9c547cba1dc1238c6e8a0c290fd62ee6e127 ]

skl_get_module_info() tries to set mconfig->module->loadable before
mconfig->module has been assigned thus flag was always set to false
and driver did not try to load module binaries.
