CVE-2022-50281
MIPS: SGI-IP27: Fix platform-device leak in bridge_platform_create()
Description
In the Linux kernel, the following vulnerability has been resolved: MIPS: SGI-IP27: Fix platform-device leak in bridge_platform_create() In error case in bridge_platform_create after calling platform_device_add()/platform_device_add_data()/ platform_device_add_resources(), release the failed 'pdev' or it will be leak, call platform_device_put() to fix this problem. Besides, 'pdev' is divided into 'pdev_wd' and 'pdev_bd', use platform_device_unregister() to release sgi_w1 resources when xtalk-bridge registration fails.
