If you're resending someone's patch, you have to add your own Signed off
by line as well.  Everyone who touches a patch has to sign that they
didn't add any of SCO's all powerful UnixWare source code into the
patch.

[PATCH v3] staging: fieldbus: core: fix ->poll() annotation

2019-05-21 Thread Sven Van Asbroeck 
From: Oscar Gomez Fuente 

->poll() functions should return __poll_t, but the fieldbus
core's poll() does not. This generates a sparse warning.

Fix the ->poll() return value, and use recommended __poll_t
constants (EPOLLxxx).
