Subject: SMSC: timeout reaches -1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2cf0dbed27af3f827a96db98c2535002902f6af0;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

SMSC: timeout reaches -1

With a postfix decrement timeouts will reach -1 rather than 0, so
the error path does not appear.
