Subject: serial: omap: Initialize platform_data
X-Git-Tag: v3.12-rc1~182^2~134
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a0a490f9df2bf7e077054c78221c6b5301681de6;p=platform%2Fkernel%2Flinux-exynos.git

serial: omap: Initialize platform_data

Otherwise serial driver would crash accessing platform_data that was
not initialized in functions like:

        serial_omap_pm(...)
        ...
        if (!state && pdata->enable_wakeup)
                   ^^^^^^^
        ...
