commit dabd14684b "PCMCIA: sa1111: remove duplicated initializers"
incorrectly moved some code into the pcmcia_jornada720_init, causing
a few build errors, and for unknown reasons, the driver lacks
an inclusion of <linux/io.h>, so we get the build errors, and more:
sa1111_jornada720.c: In function 'pcmcia_jornada720_init':
sa1111_jornada720.c:101:3: error: implicit declaration of function 'IOMEM' [-Werror=implicit-function-declaration]
GRER |= 0x00000002;
^
sa1111_jornada720.c:104:3: warning: passing argument 1 of 'sa1111_set_io_dir' from incompatible pointer type [enabled by default]
sa1111_set_io_dir(dev, pin, 0, 0);
^
This patch uses the SA1111_DEV() to convert the dev pointer to the
correct type before passing it and adds the missing include.
