Subject: [PATCH 4.4 114/132] USB: serial: keyspan_pda: fix write unthrottling
Date: Mon, 28 Dec 2020 13:49:58 +0100 [thread overview]
Message-ID: <20201228124851.918783212@linuxfoundation.org> (raw)
In-Reply-To: <20201228124846.409999325@linuxfoundation.org>
From: Johan Hovold <johan@kernel.org>
commit 320f9028c7873c3c7710e8e93e5c979f4c857490 upstream.
The driver did not update its view of the available device buffer space
until write() was called in task context. This meant that write_room()
would return 0 even after the device had sent a write-unthrottle
notification, something which could lead to blocked writers not being
woken up (e.g. when using OPOST).
Note that we must also request an unthrottle notification is case a
write() request fills the device buffer exactly.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
