ASoC: fsl-asoc-card: set priv->pdev before using it
mainline inclusion from mainline-v6.10-rc6 commit 90f3feb24172185f1832636264943e8b5e289245 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGEP3 CVE: CVE-2024-42089 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=90f3feb24172185f1832636264943e8b5e289245 ------------------------------------------- priv->pdev pointer was set after being used in fsl_asoc_card_audmux_init(). Move this assignment at the start of the probe function, so sub-functions can correctly use pdev through priv. fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the dev struct, used with dev_err macros. As priv is zero-initialised, there would be a NULL pointer dereference. Note that if priv->dev is dereferenced before assignment but never used, for example if there is no error to be printed, the driver won't crash probably due to compiler optimisations.
