Subject: [PATCH v2 05/15] serial: sc16is7xx: remove unnecessary pointer cast

From: Hugo Villeneuve <hvilleneuve@...onoff.com>

There is no need to cast from a void * pointer, so remove this cast.

Also remove empty line inavertently added in commit d5078509c8b0
("serial: sc16is7xx: improve do/while loop in sc16is7xx_irq()") and
change variables order to follow reversed xmas tree.
