Subject: cfg80211: use __force __rcu to suppress sparse warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cec3f0ed7de78c02ac4bc719a95915367d68c778;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

cfg80211: use __force __rcu to suppress sparse warning

The code assigns a constant value (a pointer to a static variable)
to an RCU pointer, which results in a sparse warning:
  reg.c:112:10: warning: cast adds address space to expression (<asn:4>)

Suppress this warning by using __force.
