From: Takashi Iwai Date: Thu, 2 Feb 2017 16:46:49 +0000 (+0100) Subject: ALSA: x86: Rename drv_status to connected X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=91b0cb0cc07bcb5114df2897531f4ea41c148c8e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ALSA: x86: Rename drv_status to connected After the rewrite of the runtime PM code, we have only two driver status: CONNECTED and DISCONNECTED. So it's clearer to use a boolean flag, and name it easier one, "connected".
