From d7e9bdcf5053c838a7421c8e52fed2a0bd4644fb Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Sun, 14 May 2006 10:01:31 +0200 Subject: Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend From: Patrick Boettcher The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver is having a field of dvb_frontend_ops in its private-state-struct and using the reference for filling the pointer-field in dvb_frontend. - It saves at least two lines of code per demod-driver, - reduces object size (one less dereference per frontend_ops-access), - be coherent with dvb_tuner_ops, - makes it a little bit easier for newbies to understand how it works and - avoids stupid mistakes because you would have to copy the dvb_frontend_ops always, before you could assign the static pointer directly, which was dangerous.
