[PATCH 20/33] staging: vc04_services: Remove VCHIQ_HEADER_T typedef

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Typedefing structs is not encouraged in the kernel.

The removal of typedefs was requested in interface/vchi/TODO in commit
7626e002225a4c1b9455689b1f22909dfeff43ca.
