Subject: [PATCH] pcmcia: add pcmcia_disable_device
X-Git-Tag: v2.6.17-rc1~14^2~16
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5f2a71fcb7995633b335a1e380ac63a968e61320;p=linux-2.6

[PATCH] pcmcia: add pcmcia_disable_device

pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary
cleanups upon device or driver removal: it calls the appropriate
pcmcia_release_* functions, and can replace (most) of the current drivers'
_release() functions.

 This file details changes in 2.6 which affect PCMCIA card driver authors:
 
+* New release helper (as of 2.6.17)
+   Instead of calling pcmcia_release_{configuration,io,irq,win}, all that's
+   necessary now is calling pcmcia_disable_device. As there is no valid
+   reason left to call pcmcia_release_io and pcmcia_release_irq, they will
+   be removed soon.
+
 * Unify detach and REMOVAL event code, as well as attach and INSERTION
   code (as of 2.6.16)
        void (*remove)          (struct pcmcia_device *dev);
