3.11-stable review patch. If anyone has any objections, please let me know. ------------------ From: Tomas Winkler <tomas.winkler@xxxxxxxxx> commit ff96066e3171acdea356b331163495957cb833d0 upstream. Both H_IS and H_IE needs to be set to receive H_RDY interrupt 1. Assert H_IS to clear the interrupts during hw reset and use mei_me_reg_write instead of mei_hcsr_set as the later strips down the H_IS 2. fix interrupt disablement embarrassing typo hcsr |= ~H_IE -> hcsr &= ~H_IE; this will remove the unwanted interrupt on power down 3. remove useless debug print outs Signed-off-by: Tomas Winkler <tomas.winkler@xxxxxxxxx> Cc: Shuah Khan <shuah.kh@xxxxxxxxxxx> Cc: Konstantin Khlebnikov <khlebnikov@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/misc/mei/hw-me.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) --- a/drivers/misc/mei/hw-me.c +++ b/drivers/misc/mei/hw-me.c @@ -176,21 +176,18 @@ static int mei_me_hw_reset(struct mei_de struct mei_me_hw *hw = to_me_hw(dev); u32 hcsr = mei_hcsr_read(hw); - dev_dbg(&dev->pdev->dev, "before reset HCSR = 0x%08x.\n", hcsr); - - hcsr |= (H_RST | H_IG); + hcsr |= H_RST | H_IG | H_IS; if (intr_enable) hcsr |= H_IE; else - hcsr |= ~H_IE; + hcsr &= ~H_IE; - mei_hcsr_set(hw, hcsr); + mei_me_reg_write(hw, H_CSR, hcsr); if (dev->dev_state == MEI_DEV_POWER_DOWN) mei_me_hw_reset_release(dev); - dev_dbg(&dev->pdev->dev, "current HCSR = 0x%08x.\n", mei_hcsr_read(hw)); return 0; } -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
