Remove obsolete pre_transfer hook in stedma40_chan_cfg. The intent of this hook is merely to handle burst size compensation for ux500 variant MMCI. Remove obsolete stedma40_set_psize since it is only called from pre_transfer. DMAEngine device_control replaces the functionality of stedma40_set_psize. Signed-off-by:

LLI allocation is now done on job level instead of channel level. Previously the maximum length of a linked job in hw on a logical channel was 8, since the LLIs where evenly divided. Now only executing jobs have allocated LLIs which increase the length to a maximum of 64 links in HW. Signed-off-by:

"param->u.wpa_associate.wpa_ie_len" comes from the user. We should check it so that the copy_from_user() doesn't overflow the buffer. Also further down in the function, we assume that if "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is initialized. To make that work, I changed the test here to say that if "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return -EINVAL. Oddly, we only use the first element of the abyWPAIE[] array. So I suspect there may be some other issues in this function. Signed-off-by:

This reverts commit 96d592ed. The netfilter hook seems to be misused and may leak skbs in situations when NF_HOOK returns NF_STOLEN. It may not filter everything as expected. Also the ethernet bridge tables are not yet capable to understand batman-adv packet correctly. It was only added for testing purposes and can be removed again. Reported-by:

The TIOCGICOUNT device ioctl in both mos7720.c and mos7840.c allows unprivileged users to read uninitialized stack memory, because the "reserved" member of the serial_icounter_struct struct declared on the stack is not altered or zeroed before being copied back to the user.

Commit 461c3177(into 2.6.36-v3) is put forward to power down phy if no usb cable is connected, but does introduce the two issues below: 1), phy is not into work state if usb cable is connected with PC during poweron, so musb device mode is not usable in such case, follows the reasons: -twl4030_phy_resume is not called, so regulators are not enabled i2c access are not enabled usb mode not configurated 2), The kernel warings[1] of regulators 'unbalanced disables' is caused if poweron without usb cable connected with PC or b-device. This patch fixes the two issues above: -power down phy only if no usb cable is connected with PC and b-device -do phy initialization(via __twl4030_phy_resume) if usb cable is connected with PC(vbus event) or another b-device(ID event) in twl4030_usb_probe. This patch also doesn't put VUSB3V1 LDO into active mode in twl4030_usb_ldo_init until VBUS/ID change detected, so we can save more power consumption than before. This patch is verified OK on Beagle board either connected with usb cable or not when poweron. [1]. warnings of 'unbalanced disables' of regulators.
