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")
