Subject: [PATCH AUTOSEL 5.4 027/205] pinctl: ti: iodelay: fix error checking on pinctrl_count_index_with_args call
Date: Thu, 16 Jan 2020 11:40:02 -0500 [thread overview]
Message-ID: <20200116164300.6705-27-sashal@kernel.org> (raw)
In-Reply-To: <20200116164300.6705-1-sashal@kernel.org>
From: Colin Ian King <colin.king@canonical.com>
[ Upstream commit 5ff8aca906f3a7a7db79fad92f2a4401107ef50d ]
The call to pinctrl_count_index_with_args checks for a -EINVAL return
however this function calls pinctrl_get_list_and_count and this can
return -ENOENT. Rather than check for a specific error, fix this by
checking for any error return to catch the -ENOENT case.
Addresses-Coverity: ("Improper use of negative")
Fixes: 003910ebc83b ("pinctrl: Introduce TI IOdelay configuration driver")
