From c344a327baefc372b7f4b7d0c17ac8b417ceaf94 Mon Sep 17 00:00:00 2001 From: Manish Narani Date: Wed, 18 Jul 2018 16:42:09 +0530 Subject: iio: adc: xilinx: Remove dead code from xadc_zynq_setup This patch removes dead code from xadc_zynq_setup. The condition "if (tck_rate > XADC_ZYNQ_TCK_RATE_MAX)" cannot be true at any point of time. There is also an incompatible parameter used in the code. This patch fixes the same reported by coverity.
