[PATCH 4.13 105/160] ALSA: compress: Remove unused variable

[Greg Kroah-Hartman]

4.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Guneshwor Singh <guneshwor.o.singh@xxxxxxxxx>

commit a931b9ce93841a5b66b709ba5a244276e345e63b upstream.

Commit 04c5d5a430fc ("ALSA: compress: Embed struct device") removed
the statement that used 'str' but didn't remove the variable itself.
So remove it.

[Adding stable to Cc since pr_debug() may refer to the uninitialized
 buffer -- tiwai]
