2012-08-10usb: ehci: tegra: Fix Slab corruption errorPreetham Chandru
Give ownership of the DMA buffer back to the processor first and then free the buffer. Otherwise processor won't be able to access the dma mapped buffers and this would lead to slab corruption. When the DMA buffer is freed without a call to dma_sync_single_for_cpu(), the kernel won't be able to set the buffer as POISON FREE and when we acquire this memory back again the kernel will start printing slab corruption output as the memory is not set to POISON FREE Bug 1017884 Bug 1018161 Reviewed-on: http://git-master/r/#change,122151 Signed-off-by: Preetham Chandru R <pchandru@nvidia.com> Change-Id: I00d6cb185cd2314cccb56f968eb0a05288588c13 Reviewed-on: http://git-master/r/122390 Reviewed-by: Simone Willett <swillett@nvidia.com> Tested-by: Simone Willett <swillett@nvidia.com>

tegra_ehci_suspend_noirq/tegra_ehci_resume_noirq breaks the modem suspend call as it does a regulator_disable()/regulator_enable call which in turn requires the irqs to be enabled. Hence maintain a normal suspend call i.e with irqs enabled but split the resume to normal resume and noirq resume. Spliting the resume in this way takes care of the below erros in lp0/lp1 "tegra-ehci tegra-ehci.2:fatal error" "tegra-ehci tegra-ehci.2: HC died; cleaning up" Originally resume_noirq & suspend_noirq were added to avoid the above errors but since it breaks the modem suspend call splitting the suspend and resume in this way Bug 954564 Signed-off-by: Preetham Chandru R <pchandru@nvidia.com> Change-Id: I630b3dbe2ca66d194857dc71ababa3e5955785b1 Reviewed-on: http://git-master/r/99100 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Bitan Biswas <bbiswas@nvidia.com>

usb driver needs to be suspended late and resumed early even before irqs are disabled/enabled. Without this change the following two issues are seen during lp0 and lp1 states. In lp0, when there is a usb wakeup event (by unplugging the usb device) we get the following error: "tegra-ehci tegra-ehci.2:fatal error" "tegra-ehci tegra-ehci.2: HC died; cleaning up" The above error comes because an irq is generated even before the usb_resume was called.
