Subject: staging: comedi: pcl816: trigger sources were validated in (*do_cmdtest)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab09248c998dd9df4f35912827d95d70b499bd30;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging: comedi: pcl816: trigger sources were validated in (*do_cmdtest)

The trigger sources were already validataed in the (*do_cmdtest) before the
(*do_cmd) is called. Remove the unnecessary checks in pcl816_ai_cmd().
