NS16550A: Restore HS settings in EXCR2 on resume
After a suspend/resume cycle, the UART may have been reset into low-speed mode -- either because it's actually been reset, or because the firmware pokes at the old-style divisor registers. If we detected it as a NS16550A SuperIO chip in the first place and set baud_base to 921600, then we should do so again in the resume path. This patch adds that code to serial8250_resume_port(), and also makes serial8250_resume() actually call serial8250_resume_port() for each port instead of just calling uart_resume_port() directly. And thus fixes serial port operation after suspend/resume. It also fixes a bogus comment where we write the EXCR2 register with a comment saying /* EXCR1 */ Signed-off-by: David Woodhouse <dwmw2@infradead.org> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
