Subject: clk: Propagate any error return from debug_init()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=abeab450bfe823079c8a3abf5123f41a0da62392;p=openwrt%2Fstaging%2Fblogic.git

clk: Propagate any error return from debug_init()

If the .debug_init op is provided, it will be called by
clk_debug_create_one(). If debug_init() returns an error code,
clk_debug_create_one() will return -ENOMEM, regardless of the
value returned from debug_init(). Tweak the code to return
the actual value returned by debug_init() instead.
