None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2014-01-07hso: fix handling of modem port SERIAL_STATE notificationsDan Williams1-2/+11
The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port. Signed-off-by: Dan Williams <dcbw@redhat.com> Tested-by: H.

2014-01-01usbnet: mcs7830: rework link state detectionOctavian Purdila1-15/+4
Even with the quirks in commit dabdaf0c (mcs7830: Fix link state detection) there are still spurious link-down events for some chips where the false link-down events count go over a few hundreds. This patch takes a more conservative approach and only looks at link-down events where the link-down state is not combined with other states (e.g. half/full speed, pending frames in SRAM or TX status information valid). In all other cases we assume the link is up. Tested on MCS7830CV-DA (USB ID 9710:7830).

2013-12-19dm9601: work around tx fifo sync issue on dm962xPeter Korsgaard1-8/+19
Certain dm962x revisions contain an bug, where if a USB bulk transfer retry (E.G. if bulk crc mismatch) happens right after a transfer with odd or maxpacket length, the internal tx hardware fifo gets out of sync causing the interface to stop working. Work around it by adding up to 3 bytes of padding to ensure this situation cannot trigger. This workaround also means we never pass multiple-of-maxpacket size skb's to usbnet, so the length adjustment to handle usbnet's padding of those can be removed.

2013-11-21r8152: support stopping/waking tx queuehayeswang1-0/+22

2013-11-21r8152: fix tx/rx memory overflowhayeswang1-13/+17
The tx/rx would access the memory which is out of the desired range. Modify the method of checking the end of the memory to avoid it. For r8152_tx_agg_fill(), the variable remain may become negative. However, the declaration is unsigned, so the while loop wouldn't break when reaching the end of the desied memory. Although to change the declaration from unsigned to signed is enough to fix it, I also modify the checking method for safe. Replace remain = rx_buf_sz - sizeof(*tx_desc) - (u32)((void *)tx_data - agg->head); with remain = rx_buf_sz - (int)(tx_agg_align(tx_data) - agg->head); to make sure the variable remain is always positive. Then, the overflow wouldn't happen. For rx_bottom(), the rx_desc should not be used to calculate the packet length before making sure the rx_desc is in the desired range. Change the checking to two parts. First, check the descriptor is in the memory. The other, using the descriptor to find out the packet length and check if the packet is in the memory.

This is harmless but cdc_ncm_setup() returns negative error codes truncated to u8 values. There is only one caller and treats all non-zero returns as errors but doesn't store the the return code.

2013-11-14usbnet: fix status interrupt urb handlingFelix Fietkau1-3/+0
Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf "sierra_net: keep status interrupt URB active", sierra_net triggers status interrupt polling before the net_device is opened (in order to properly receive the sync message response). To be able to receive further interrupts, the interrupt urb needs to be re-submitted, so this patch removes the bogus check for netif_running().

There are MBIM devices out there reporting dwNtbInMaxSize=2048 dwNtbOutMaxSize=2048 and since the spec require a datagram max size of at least 2048, this means that a full sized datagram will never fit.
