Subject: ds1wm: should check for IS_ERR(clk) instead of NULL
X-Git-Tag: v2.6.25-rc4~67

ds1wm: should check for IS_ERR(clk) instead of NULL

On the error condition clk_get() returns ERR_PTR(..), so checking for NULL
doesn't work.  ds1wm module causes a kernel oops when ds1wm clock isn't
registered.

This patch converts NULL check to IS_ERR(), plus uses PTR_ERR()
for the return code.
