Subject: [PATCH 4/7] atmel-isi: fix IS_ERR_VALUE usage
Date: Mon, 15 Feb 2016 15:35:22 +0100 [thread overview]
Message-ID: <1455546925-22119-5-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <1455546925-22119-1-git-send-email-a.hajda@samsung.com>
IS_ERR_VALUE macro should be used only with unsigned long type.
For signed types comparison 'ret < 0' should be used.
The patch follows conclusion from discussion on LKML [1][2].
