ALSA: hda_intel: add card number to irq description
Currently the info in /proc/interrupts doesn't allow to figure out which interrupt belongs to which card (HDMI, PCH, ..). Therefore add card details to the interrupt description. With the patch the info in /proc/interrupts looks like this: PCI-MSI 442368-edge snd_hda_intel:card1 PCI-MSI 49152-edge snd_hda_intel:card0 NOTE: this patch adds the new irq_descr field snd_card struct that is filled automatically at a card object creation. This can be used generically for other drivers as well. The changes for others will follow later -- tiwai Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
