Subject: [PATCH] ppc32: i8259 PIC should not be initialized if PCI is not configured
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6cf2b3fc9934a56ceeb393ea5d0149e0bebc80fa;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] ppc32: i8259 PIC should not be initialized if PCI is not configured

Trying to initialize the i8259 PIC will not work if CONFIG_PCI is not
enabled.  The kernel hangs if the initialization is tried.
