From: Thomas Gleixner <t...@linutronix.de> in_interrupt() is ill defined and does not provide what the name suggests. The usage especially in driver code is deprecated and a tree wide effort to clean up and consolidate the (ab)usage of in_interrupt() and related checks is happening.
In this case the check covers only parts of the contexts in which these functions cannot be called. It fails to detect preemption or interrupt disabled invocations. As the functions which are invoked from at*_reinit_locked() contain a broad variety of checks (always enabled or debug option dependent) which cover all invalid conditions already, there is no point in having inconsistent warnings in those drivers. Just remove them. Signed-off-by: Thomas Gleixner <t...@linutronix.de> Cc: "David S.
