From bbcd85a0e624a6825e2b4477a5ad2a7873288809 Mon Sep 17 00:00:00 2001 From: Vivek Gautam Date: Tue, 9 Apr 2013 18:42:11 +0530 Subject: [PATCH] usb: ehci-s5p: fix: Fix null pointer dereferencing 7edb3da: (USB: EHCI: make ehci-s5p a separate driver) raised an issue with ehci-s5p's driver data. Now that 's5p_ehci_hcd' doesn't maintain pointer to 'usb_hcd' and s5p_ehci is nothing but a pointer to hcd->priv; add hcd to the driver data rather than s5p_ehci. This fixes issues with null pointer dereferencing in s5p_ehci_shutdown(), s5p_ehci_suspend(), s5p_ehci_resume().
