From: Ian Abbott Date: Tue, 29 May 2012 13:49:31 +0000 (+0100) Subject: staging: comedi: amplc_pc236: Replace printk calls X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62bc23d145d636f0de2bf412dcf31a33fcf16046;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: amplc_pc236: Replace printk calls Replace the printk calls with dev_info, dev_err, etc. There were some consecutive printk calls without newlines which now scnprintf into a temporary buffer and this bit of code has been factored out into new function pc236_report_attach().
