X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7cecb53b5094f2606161bad469c63989b0394e86;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

soc: qcom: scm_qcpe: use uninterruptible habmm_socket_recv()

This is necessary to support scm call in system shutdown
procedure. With interruptible habmm_socket_recv(), it will
return immediately without blocking until the response
arrives.
