Subject: [PATCH 0/3] USB: serial: return errors from break handling
Date: Fri, 2 Jun 2023 14:46:39 +0200 [thread overview]
Message-ID: <20230602124642.19076-1-johan@kernel.org> (raw)
This series starts returning errors from break handling and also uses
that mechanism to report to user space when break signalling is not
supported (e.g. when device or driver support is missing).
Note that the tty layer currently returns early but without reporting
errors when a tty driver does not support break signalling. The intent
expressed in commit 9e98966c7bb9 ("tty: rework break handling") from
2008 appears to be to allow missing support to be reported to user
space however.
