xhci: hsic: Enable xhci irq after xhci memory initialization (672ab146) · Commits · e / devices / android_kernel_sony_msm8994

Spurious port change interrupt is causing access to xhci data structures from xhci_irq() which causes memory corruption. Avoid this by enabling xhci irq right before enabling HSIC phy drives idle state on to the bus. CRs-Fixed: 669583 Change-Id: I35bf904859fda7ad41df8e40b86338395adf2099 Signed-off-by:
