From 3b37a15c2d75585cc0da49b8e69345af91e227ce Mon Sep 17 00:00:00 2001 From: Manu Abraham Date: Mon, 20 Oct 2008 18:14:14 -0300 Subject: V4L/DVB (9346): Optimization: Enable gate in a symmetric/disciplined way, rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well. Improves readability on the device control.

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with 2.6.24, I was met with an oops [1]. The problem is relevant to 2.6.25/26-rc also. dvb_frontend_init() was called either from re-creation of the kdvb-fe0 thread - seems unlikely, or someone called dvb_frontend_reinitialise(), causing this path in the thread - really unlikely, as I can't find any call-site for it. Either way, quite a number of drivers call dvb_usb_generic_rw() [2] without checking the validity of the relevant member in the dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw() sanity-check and fail (rather than loading from 0x120) seems reasonable defensive programming [3], in light of it being called in this way. The problem with this, is that drivers don't check the return code of the init call [4]. Does it make sense to cook a patch which allows the failure to be propagated back up, or am I missing something else?
