From: Marcel Holtmann Date: Fri, 13 Mar 2015 17:20:35 +0000 (-0700) Subject: Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flags X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7cb93e52839ee44959adabc17c2a17422e6bd4b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flags With the extension of hdev->dev_flags utilizing a bitmap now, the space is no longer restricted. Merge the hdev->dbg_flags into hdev->dev_flags to save space on 64-bit architectures. On 32-bit architectures no size reduction happens.
