Exists in smarc-l5.0.0_1.0.0-ga and in 5 other branches imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga

mISDN: DSP scheduling fix (version 2) 

dsp_spl_jiffies need to be the same datatype as jiffies (which is ulong).
If not, on 64 bit systems it will fallback to schedule the DSP every jiffie
tic as soon jiffies become > 2^32.
