From: Ian Abbott Date: Thu, 31 May 2012 15:02:03 +0000 (+0100) Subject: staging: comedi: amplc_pci224: Replace printk calls X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eedc1b7be2ea7c8350f359ff9afa568cb89a70d7;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: comedi: amplc_pci224: 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 pci224_report_attach(). A couple of DPRINTK() macro calls which may result in printk() calls have been left alone to be tackled en masse at a later date.
