Aleksandr Mishin cff3cbba73 platform/x86: dell-smbios: Fix error path in dell_smbios_init() ... [ Upstream commit ffc17e1479e8e9459b7afa80e5d9d40d0dd78abb ] In case of error in build_tokens_sysfs(), all the memory that has been allocated is freed at end of this function. But then free_group() is called which performs memory deallocation again. Also, instead of free_group() call, there should be exit_dell_smbios_smm() and exit_dell_smbios_wmi() calls, since there is initialization, but there is no release of resources in case of an error. Fix these issues by replacing free_group() call with exit_dell_smbios_wmi() and exit_dell_smbios_smm(). Found by Linux Verification Center (linuxtesting.org) with SVACE.
