Subject: [PATCH 2/2] staging: rts_pstor: set lun_mode in a different place

From: wwang <wei_wang@...lsil.com.cn>

In sony notebook, card reader will be configured as two-lun mode
through EFUSE. In this situation, MS card can't be recognized
properly because driver does only support single-lun mode in default.
In this patch, lun_mode is set in a different place, so driver can
detect the EFUSE configuation automatically.
