Subject: pcmcia: stop updating dev->power.power_state
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6b4fa6d698f5cf331ead08db4ba5e60cd3c83be;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

pcmcia: stop updating dev->power.power_state

This stops the pcmcia core from using dev->power.power_state; that field is
deprecated (overdue for removal) and the only reason to update it was to make
the /sys/devices/.../power/state files (now removed) work better.
