Subject: pcmcia: give socket time to power down
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afb2c1650b4c6f285596268d0a1de2a81542a765;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

pcmcia: give socket time to power down

Give sockets up to 100ms of additional time to power down.  otherwise we
might generate false warnings with KERN_ERR priority (like in bug #8262).
