Subject: [PATCH] thermal: tsens: Remove unnecessary comparison of unsigned integer with < 0
Date: Mon, 27 May 2019 11:08:25 -0500 [thread overview]
Message-ID: <20190527160825.GA24219@embeddedor> (raw)
There is no need to compare hw_id with < 0 because such comparison
of an unsigned value is always false.
Fix this by removing such comparison.
Addresses-Coverity-ID: 1445440 ("Unsigned compared against 0")
Fixes: 3e6a8fb33084 ("drivers: thermal: tsens: Add new operation to check if a sensor is enabled")
