From: William Breathitt Gray Date: Wed, 8 Feb 2023 10:55:42 +0000 (-0500) Subject: gpio: 104-dio-48e: Utilize mask_buf_def in handle_mask_sync() callback X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b961b2aa2f64a828a77749b82989ba2968cdf344;p=linux.git gpio: 104-dio-48e: Utilize mask_buf_def in handle_mask_sync() callback The mask_buf_def argument provides a mask of all the maskable lines. Utilize mask_buf_def rather than hardcode an "all_masked" mask.
