[Xen-devel] [PATCH] xen/privcmd: remove unused variable pageidx

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable pageidx is assigned a value but it is never read, hence it
is redundant and can be removed. Cleans up clang warning:

drivers/xen/privcmd.c:199:2: warning: Value stored to 'pageidx'
is never read
