2011-03-28hp-wmi: clear rfkill device pointers when appropriateAnssi Hannula1-0/+8
NULLify rfkill pointers during initialization. This prevents dereference of invalid pointer in case the driver is rebound and some rfkill device isn't detected anymore. Clear them also in hp_wmi_rfkill_setup failure path so that an rfkill initialization failure doesn't need to be fatal for the whole driver.

2011-03-28hp-wmi: split rfkill initialization out of hp_wmi_bios_setupAnssi Hannula1-17/+29
Split initialization of rfkill devices from hp_wmi_bios_setup() to hp_wmi_rfkill_setup(). This makes the code somewhat cleaner, especially with the future command 0x1b rfkill support. Signed-off-by: Anssi Hannula <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>
2011-03-28hp-wmi: allow setting input and output buffer sizes separatelyAnssi Hannula1-24/+39
Split buffersize parameter of hp_wmi_perform_query to insize and outsize. Existing callers are changed to use the same value for insize and outsize to avoid any regressions, with the exception of hp_wmi_set_block where the output buffer is unused and therefore outsize is set to 0 (this change is not seen by BIOS code). The maximum input buffer size is kept at 4 bytes as per struct bios_args. Some commands exist that take longer buffers, but they haven't been implemented. The data portion of bios_args can be trivially made dynamically allocated later when such larger buffers become needed.

2011-03-28hp-wmi: remove a variable that is never readAnssi Hannula1-2/+1
Remove the status variable from hp_wmi_perform_query which holds the return value from wmi_evaluate_method(). It is never checked as the function bails out if the output buffer hasn't been allocated which indicates the call failed.

2011-03-28asus-laptop: remove deprecated interfaces (lcd_switch and display_get)Corentin Chary1-160/+3
I should have done that one year ago, so it's more than time to do it. These two features use non-standard interfaces. There are the only features that really need multiple path to guess what's the right method name on a specific laptop. Removing them allow to remove a lot of code an significantly clean the driver. This will affect the backlight code which won't be able to know if the backlight is on or off. The platform display file will also be write only (like the one in eeepc-laptop).

2011-03-28eeepc-wmi: serialize access to wmi methodCorentin Chary1-6/+72
\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

2011-03-28eeepc-wmi: add hotplug code for Eeepc 1000HCorentin Chary1-1/+273
Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by: Corentin Chary <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>

2011-03-27net: fix ethtool->set_flags not intended -EINVAL return valueStanislaw Gruszka5-7/+7
After commit d5dbda23804156ae6f35025ade5307a49d1db6d7 "ethtool: Add support for vlan accleration.", drivers that have NETIF_F_HW_VLAN_TX, and/or NETIF_F_HW_VLAN_RX feature, but do not allow enable/disable vlan acceleration via ethtool set_flags, always return -EINVAL from that function. Fix by returning -EINVAL only if requested features do not match current settings and can not be changed by driver. Change any driver that define ethtool->set_flags to use ethtool_invalid_flags() to avoid similar problems in the future (also on drivers that do not have the problem).

2011-03-27can: c_can: Fix tx_bytes accountingJan Altenberg1-1/+1
The current SocketCAN implementation for the Bosch c_can cell doesn't account the TX bytes correctly, because it calls c_can_inval_msg_object() (which clears the msg ctrl register) before reading the DLC value: for (/* nix */; (priv->tx_next - priv->tx_echo) > 0; priv->tx_echo++) { msg_obj_no = get_tx_echo_msg_obj(priv); c_can_inval_msg_object(dev, 0, msg_obj_no); val = c_can_read_reg32(priv, &priv->regs->txrqst1); if (!(val & (1 << msg_obj_no))) { can_get_echo_skb(dev, msg_obj_no - C_CAN_MSG_OBJ_TX_FIRST); stats->tx_bytes += priv->read_reg(priv, &priv->regs->ifregs[0].msg_cntrl) & IF_MCONT_DLC_MASK; stats->tx_packets++; } } So, we will always read 0 for the DLC value and "ifconfig" will report *0* TX Bytes. The fix is quite easy: Just move c_can_inval_msg_object() to the end of the if() statement. So: * We only call c_can_inval_msg_object() if the message was actually transmitted * We read out the DLC value _before_ clearing the msg ctrl register Signed-off-by: Jan Altenberg <[email protected]> Acked-by: Kurt Van Dijck <[email protected]> Acked-by: Wolfgang Grandegger <[email protected]> Signed-off-by: David S.
