Subject: [PATCH] debug_ll: ns16550: Fix interrupt disable on init
Date: Mon,  4 Oct 2021 09:38:42 +0200
Message-ID: <20211004073842.14809-1-jmaselbas@kalray.eu> (raw)

The debug_ll_write_reg function takes first the register
and secondly the value to write, which in this call were
inverted. Fix the argument order.
