New Revision: 219684
URL: http://svn.freebsd.org/changeset/base/219684
Log:
Fix mv_gpio_in() for pin numbers that occupy bits 8-31 in GPIO registers.
The compiler will truncate the 32-bit return value of mv_gpio_value_get()
to match the 8-bit return value of mv_gpio_in(). A conditional expression
is used to have mv_gpio_in() always return 0 or 1 instead.
