Subject: ASoC: hdac_hdmi: Potential NULL deref in hdac_hdmi_get_spk_alloc()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8f658815da156a9239b98b34e5ba1d3db71a2f6e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ASoC: hdac_hdmi: Potential NULL deref in hdac_hdmi_get_spk_alloc()

We intended || here instead of &&.  The original code potentially leads
to a NULL dereference.
