[PATCH 4.4 32/56] serial: sprd: correct the wrong sequence of arguments

From: Greg Kroah-Hartman
Date: Thu Sep 19 2019 - 18:23:20 EST


From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx>

commit 9c801e313195addaf11c16e155f50789d6ebfd19 upstream.

The sequence of arguments which was passed to handle_lsr_errors() didn't
match the parameters defined in that function, &lsr was passed to flag
and &flag was passed to lsr, this patch fixed that.

Fixes: b7396a38fb28 ("tty/serial: Add Spreadtrum sc9836-uart driver support")
