From 56d74dd5f7ad8b6b0979ce915d51cf03bcc57267 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sat, 22 Nov 2008 17:36:54 +0000 Subject: tricky one: hisax sections a) hisax_init_pcmcia() needs to be defined only if we have CONFIG_HOTPLUG (no PCMCIA support otherwise) and can be declared __devinit. b) HiSax_inithardware() can go __init c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card(): checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card); The problem with it is that * hisax_cs_setup_card() is __devinit * hisax_register() is not * hisax_cs_setup_card() is a switch from hell, calling a lot of setup_some_weirdcard() depending on card->typ. _These_ are also __devinit. However, in hisax_register() we have card->typ equal to ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind all that crap, just do nothing and return 2". So we add a trimmed-down callback doing just that and passed to checkcard() by hisax_register(). _This_ is non-init (we can stand the impact on .text size).
