From: Bard Liao Date: Sun, 26 May 2019 16:58:34 +0000 (+0800) Subject: ALSA: hda: move polling_mode flag to struct hdac_bus X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8af42130b50c4d38f48fa82f3f7be4606d01f595;p=linux.git ALSA: hda: move polling_mode flag to struct hdac_bus polling mode is a useful function in the get_response function. Move polling_mode flag from struct azx to struct hdac_bus so people can implement polling mode in their own get_response function without adding a polling_mode flag in their local chip structure.
