| |
Commit 3862828a903d3 ("iio: buffer: Switch to bitmap_zalloc()") introduced bitmap_alloc(), but commit 20ea39ef9f2f9 ("iio: Fix scan mask selection") reverted it.
This change adds it back. The only difference is that it's adding bitmap_zalloc(). There might be some changes later that would require initializing it to zero. In any case, now it's already zero-ing the trialmask.
