From 956a711c158cab42c3b3c3ab018dacd91d7440e9 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Fri, 21 Nov 2008 10:36:06 +0000 Subject: [PATCH] [ARM] S3C: Fix scaler1 clock rate information The pwm-scaler0 and pwm-scaler1 clocks have their .id field set to -1 as they are not referenced to any specific device. However, parts of the pwm-clock code used the .id field to identify which scaler clock was being used. Fix the problem by comparing against the pointer to the clock to identify the scalers.
