Subject: USB regression in v3.12-rc4

Hi,

With v3.12-rc4 I can no longer connect to N800 (OMAP2) with USB
(peripheral, g_ether).

According to git bisect this is caused by:

9b0a1de3c85d99d881c86a29b3d52da7b9c7bd61 is the first bad commit
commit 9b0a1de3c85d99d881c86a29b3d52da7b9c7bd61

    usb: musb: gadget: fix otg active status flag

    In gadget mode, musb->is_active should be set only when connected to the
    host. musb_g_reset() already takes care of it.

Reverting that commit from v3.12-rc4 will fix the issue. Based on the
commit log this is not fixing any real issue, so I wonder why was it
included in -rc4 in the first place?
