Description
In the Linux kernel, the following vulnerability has been resolved:
mfd: davinci_voicecodec: Fix possible null-ptr-deref davinci_vc_probe()
It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.
Affected configurations
• linux linux kernel (>= 5.4 < 5.4.198)
• linux linux kernel (>= 5.5 < 5.10.121)
• linux linux kernel (>= 5.11 < 5.15.46)
• linux linux kernel (>= 5.16 < 5.17.14)
• linux linux kernel (>= 5.18 < 5.18.3)
