[alsa-devel] [PATCH 2/2] ASoC: Intel: Skylake: Remove driver debugfs exit

[Guneshwor Singh]

From: Vinod Koul <vinod.koul at intel.com>

For driver debugfs, debugfs_remove_recursive() is called which is not
needed as it is already done in ASoC core debugfs. And a device managed
memory need not be freed explicitly as device core frees it up. So
remove unnecessary skl_debugfs_exit().

Fixes: 5cdf6c09ca9d ASoC: ("Intel: Skylake: Add debugfs support")
