Summary
ASoC: meson: axg-card: fix 'use-after-free'
Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: meson: axg-card: fix 'use-after-free'

Buffer 'card->dai_link' is reallocated in 'meson_card_reallocate_links()', so move 'pad' pointer initialization after this function when memory is already reallocated.

Kasan bug report:
