Subject: [PATCH 37/50] unicore32: Remove unused pmode argument in c_backtrace()
Date: Wed,  6 Nov 2019 03:05:28 +0000	[thread overview]
Message-ID: <20191106030542.868541-38-dima@arista.com> (raw)
In-Reply-To: <20191106030542.868541-1-dima@arista.com>

The pmode parameter isn't used in assembly - remove it.
Second argument will be reused for printk() log level.
