Subject: printk: Add a DEPRECATED macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a9a8bfd29aa5ba2298dc80852cdbb63a42f6576;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

printk: Add a DEPRECATED macro

sctp has several points in its setsockopt path in which it issues deprecation
warnings.  It seems like it might be handy to macrotize such a warning so other
subsystems can use it easily
