[PATCH] serial: sh-sci: remove check for zero baud rate from uart_get_baud_rate()

Posted by Hugo Villeneuve 4 days, 5 hours ago

From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

The minimum baud rate supported by this driver is 0, so even for the B0
case, uart_get_baud_rate() will return 9600, not zero. This check is no
longer necessary since commit 16ae2a877bf4 ("serial: Fix crash if the
minimum rate of the device is > 9600 baud") so remove it.
