Subject: [PATCH AUTOSEL 5.1 29/51] ASoC: Intel: cht_bsw_nau8824: fix kernel oops with platform_name override

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

[ Upstream commit 096701e8131425044d2054a0c210d6ea24ee7386 ]

The platform override code uses devm_ functions to allocate memory for
the new name but the card device is not initialized. Fix by moving the
init earlier.
