Subject: sysctl extern cleanup: sg
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=15485a4682d1d3bfee2aa78b4b1a5d36f5746b64;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

sysctl extern cleanup: sg

Extern declarations in sysctl.c should be moved to their own header file,
and then include them in relavant .c files.

Move sg_big_buff extern declaration to scsi/sg.h
