gpio/gpio-pl061: No need of thaw and poweroff routines for hibernate
pl061 uses same routines for suspend/freeze/poweroff and resume/thaw/restore. We are only saving and restoring register values on these routines. During hibernation, in freeze() we take a snapshot of gpio registers. In thaw() we don't actually need to restore these registers, as power was never shut down till now. Similarly, in poweroff() we don't need to take snapshot of these registers again, as it was done during freeze() and by now the image is already saved on disk. This patch passes poweroff() and thaw() routines as NULL to avoid this extra work done. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
