Subject: caif: remove unneeded null check in caif_connect()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f5d72af9f3dfea67f014f880d00665f96622f57f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

caif: remove unneeded null check in caif_connect()

We already dereferenced uaddr towards the start of the function when we
checked that "uaddr->sa_family != AF_CAIF".  Both the check here and the
earlier check were added in bece7b2398d0: "caif: Rewritten socket
implementation".  Before that patch, we assumed that we recieved a valid
pointer for uaddr, and based on that, I have removed this check.
