[PATCH 0/3] Staging: Remove unused functions

[Bhumika Goyal]

This patchset removes some unused functions and their prototypes since
they are not being called anywhere in the kernel.
Grepped to find the occurences.

[PATCH 1/3] Staging: rtl8712: Remove function r8712_SetTxAGCOffset and mp_start_joinbss

[Bhumika Goyal]

The functions r8712_SetTxAGCOffset and mp_start_joinbss are not used
anywhere in the kernel so remove their definitions and prototypes.
