Subject: [PATCH] ASoC: zx-tdm: remove redundant assignment to ts_width on error return path

From: Colin Ian King <colin.king@...onical.com>

The value assigned to ts_width is never read on the error return path
so the assignment is redundant and can be removed.  Remove it.

Addresses-Coverity: ("Unused value")
