All being well this means that it will be integrated into the linux-next

the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing

Subject: [PATCH] ASoC: Intel: Skylake: fix uninitialized pointer use

The error handling in bxt_sst_dsp_init() got changed in a way that
it now derefences an uninitialized pointer when printing a warning
about the device not being found:

sound/soc/intel/skylake/bxt-sst.c: In function 'bxt_sst_dsp_init':
sound/soc/intel/skylake/bxt-sst.c:567:14: error: 'skl' may be used uninitialized in this function [-Werror=maybe-uninitialized]

As we do have a valid device pointer available at the call site,
let's use that instead.
