Subject: [PATCH 1/3] iio: stmpe-adc: Remove unnecessary assignment
Date:   Fri,  3 May 2019 15:57:23 +0200

From: Philippe Schenker <philippe.schenker@toradex.com>

Remove unnecessary assignment. This could potentially cause an issue, if
the wait function runs into a timeout. Furthermore is this assignment also
not there in stmpe_read_temp()
