2013-06-18brcmfmac: remove redundant chip ID check in dhd_sdioFranky Lin
There is an ID table registered to SDIO stack which consists of all SDIO devices supported by brcmfmac. It is not necessary to have an extra check.

2013-06-17mwifiex: fix memory corruption when unsetting multicast listDaniel Drake
When trying to unset a previously-set multicast list (i.e. the new list has 0 entries), mwifiex_set_multicast_list() was calling down to mwifiex_request_set_multicast_list() while leaving mcast_list.num_multicast_addr as an uninitialized value. We were arriving at mwifiex_cmd_mac_multicast_adr() which would then proceed to do an often huge memcpy of mcast_list.num_multicast_addr*ETH_ALEN bytes, causing memory corruption and hard to debug crashes. Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast list is provided. Similarly, fix up the logic in mwifiex_request_set_multicast_list() to unset the multicast list that was previously sent to the hardware in such cases.

2013-06-17wlcore: fix occasional AP TX stop after recoveryVictor Goldenshtein
The fw_status wasn't zeroed during allocation, resulting in uninitialized var usage, and finally causing AP traffic stop after recovery. The wrong value in fw_status_2->counters.tx_lnk_free_pkts led to a bad lnk->allocated_pkts calculation in wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return FALSE (lnk->allocated_pkts > thold). This eventually blocked the link in wlcore_tx_work_locked(), as wl1271_skb_dequeue() continuously returned NULL. Fix it by zeroing wl->fw_status_1/2 during allocation.

2013-06-17wl18xx: FDSP Code RAM Corruption fixIdo Reis
In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets corrupted when exiting from ELP mode. This issue is related to FDSP Code RAM clock implementation. PG2.1 introduces a HW fix for this issue that requires the driver to change the FDSP Code Ram clock settings (mux it to ATGP clock instead of its own clock). This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8 PG2.1 devices. The fix is also backward compatible with older PG2.0 devices where the register PHY_FPGA_SPARE_1 is not used and not connected. The fix is done in the wl18xx_pre_upload function (must be performed before uploading the FW code) and includes the following steps: 1. Disable FDSP clock 2. Set ATPG clock toward FDSP Code RAM rather than its own clock. 3.

2013-06-14Merge tag 'nfc-next-3.11-1' of ↵John W. Linville
git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next Samuel Ortiz <sameo@linux.intel.com> says: "These are the pending NFC patches for the 3.11 merge window. It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2), along with a few more for the pn544 and pn533 drivers, the LLCP disconnection path and an LLCP memory leak. Highlights for this one are: - An initial secure element API. NFC chipsets can carry an embedded secure element or get access to the SIM one. In both cases they control the secure elements and this API provides a way to discover, enable and disable the available SEs. It also exports that to userspace in order for SE focused middleware to actually do something with them (e.g. payments). - NCI over SPI support. SPI is the most complex NCI specified transport layer and we now have support for it in the kernel. The next step will be to implement drivers for NCI chipsets using this transport like e.g. bcm2079x. - NFC p2p hardware simulation driver. We now have an nfcsim driver that is mostly a loopback device between 2 NFC interfaces. It also implements the rest of the NFC core API like polling and target detection. This driver, with neard running on top of it, allows us to completely test the LLCP, SNEP and Handover implementation without physical hardware. - A Firmware update netlink API. Most (All ?) HCI chipsets have a special firmware update mode where applications can push a new firmware that will be flashed. We now have a netlink API for providing that mode to e.g. nfctool."
