From 9900073cf5587662df9b7ef59f649ff100229d85 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Sat, 28 Jan 2017 17:10:43 +0200 Subject: pwm: lpss: Do not export board infos for different PWM types The PWM LPSS probe drivers just pass a pointer to the exported board info structures to pwm_lpss_probe() based on device PCI or ACPI ID. In order to remove the knowledge of specific devices from library part of the driver and reduce noise in exported namespace just duplicate the board info structures and stop exporting them.
