[PATCH] staging: iio: fix compile error

[Arnd Hannemann]

Commit b46413367961c2e8bd827e067a231be982aaeee2 introduced the following compile error:

  CC      drivers/staging/iio/industrialio-core.o
linux-2.6/drivers/staging/iio/industrialio-core.c: In function 'iio_event_getfd':
linux-2.6/drivers/staging/iio/industrialio-core.c:262:32: error: 'ev_int' undeclared (first use in this function)
linux-2.6/drivers/staging/iio/industrialio-core.c:262:32: note: each undeclared identifier is reported only once for each function it appears in

This patch fixes that.

Thanks though this is fix number 4 I think. One will hit Linux next today and Greg has one to push out to Linus.

Arrgh...  My fault, sorry.  Might be worth using the same local variable
for setting the bit as well...
