Subject: [PATCH 14/18] mtd-cfi_cmdset_0002: Use common error handling code in do_write_oneword()
Date: Wed, 11 Jan 2017 21:49:27 +0100 [thread overview]
Message-ID: <63f5abca-b47b-75b5-ee7c-7430f589ced0@users.sourceforge.net> (raw)
In-Reply-To: <71189baa-8780-b80a-0b4d-9dae74763ba3@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 11 Jan 2017 19:08:01 +0100
Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
