From 0b6a2c9cf4a00f54a0916499ece8a5cf3cced385 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 1 Feb 2019 12:14:53 +0100 Subject: ALSA: isa: Avoid passing NULL to memory allocators We used to pass NULL to memory allocators for ISA devices due to historical reasons. But we prefer rather a proper device object to be assigned, so let's fix it by replacing snd_dma_isa_data() call with card->dev reference, and kill snd_dma_isa_data() definition.
