category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8ICOU
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/coresight/linux.git/commit/?h=fixes&id=862c135bde8bc185e8aae2110374175e6a1b6ed5



---------------------------------------------------------------------------

In smb_reset_buffer, the sdb->buf_hw_base variable is uninitialized
before use, which initializes it in smb_init_data_buffer. And the SMB
regiester are set in smb_config_inport.
So move the call after smb_config_inport.
