Alexey Khoroshilov a3d5fcc6cf mISDN: Fix memory leak in dsp_pipeline_build()
[ Upstream commit c6a502c2299941c8326d029cfc8a3bc8a4607ad5 ]

dsp_pipeline_build() allocates dup pointer by kstrdup(cfg),
but then it updates dup variable by strsep(&dup, "|").
As a result when it calls kfree(dup), the dup variable contains NULL.

Found by Linux Driver Verification project (linuxtesting.org) with SVACE.
