CVE-2022-48756

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dsi: invalid parameter check in msm_dsi_phy_enable The function performs a check on the "phy" input parameter, however, it is used before the check. Initialize the "dev" variable after the sanity check to avoid a possible NULL pointer dereference. Addresses-Coverity-ID: 1493860 ("Null pointer dereference")
