Subject: can: ti_hecc: Fix unintialized variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f288cc52f478e6f58d96158e7cd857fedb6d111;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

can: ti_hecc: Fix unintialized variable

In ti_hecc_xmit(), local variable "data" is not initialized before
being used.
This initialization got inadvertently removed in the following patch:

	can: Unify droping of invalid tx skbs and netdev stats
