Subject: [PATCH] Call init_timer() for ISDN PPP CCP reset state timer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dab6df63086762629936e8b89a5984bae39724f6;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] Call init_timer() for ISDN PPP CCP reset state timer

The function isdn_ppp_ccp_reset_alloc_state() sets ->timer.function
and ->timer.data and later on calls add_timer() with no init_timer()
ever done.
