Subject: [PATCH 2/2] staging: dgnc: switch timeout to signed type

The schedule_timeout*() helpers take the timeout as signed long, as
ch_close_delay in struct channel_t was not used for other purposes its
type was switched to signed long and the declarations fixed up.

Patch was compile tested with x86_64_defconfig + CONFIG_STAGING=y,
CONFIG_DGNC=m

Patch is against 4.1-rc5 (localversion-next is -next-20150529)

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>

Note that there is a "over 80 char" warning here that was not fixed as
there are quite a few in dgnc_driver.h.
