Subject: [PATCH 4.9 20/30] serial: sprd: adjust TIMEOUT to a big value
Date: Tue, 26 Mar 2019 15:29:59 +0900 [thread overview]
Message-ID: <20190326042608.252436998@linuxfoundation.org> (raw)
In-Reply-To: <20190326042607.558087893@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Qiao <wei.qiao@spreadtrum.com>
commit e1dc9b08051a2c2e694edf48d1e704f07c7c143c upstream.
SPRD_TIMEOUT was 256, which is too small to wait until the status
switched to workable in a while loop, so that the earlycon could
not work correctly.
