Subject: ARM: keystone: Drop the un-necessary dsb from keystone_cpu_smc()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c2dce2cf488ca8061df54733803ed5d508e8445b;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

ARM: keystone: Drop the un-necessary dsb from keystone_cpu_smc()

This was added because of some legacy reasons from OMAP SOCs but
after testing and verifying with the keystone hardware folks, the
dsb in keystone_cpu_smc() is not necessary.

So drop it.
