From c0a99bbb1b7a11605a53f84f5c444be3ef25a8ab Mon Sep 17 00:00:00 2001

Subject: [PATCH] rtl8xxxu: Clean up llt_init() API

Remove last_tx_page argument from the llt_init() function. The
rtl8xxxu_fileops structure contains the correct TX_TOTAL_PAGE_NUM
value for the device, and rtl8xxxu_auto_llt_table() doesn't need to
know the value in the first place.
