From: Geert Uytterhoeven Date: Fri, 29 May 2015 16:35:31 +0000 (+0200) Subject: PM / clk: Print acquired clock name in addition to con_id X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f17f4adfe48b64b23247b792c0e5ab998b7ab34e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git PM / clk: Print acquired clock name in addition to con_id Currently the con_id of the acquired clock is printed for debugging purposes. But in several cases, the con_id is NULL, which doesn't provide much debugging information when printed. These cases are: - When explicitly passing a NULL con_id (which means the first clock tied to the device, if available), - When not using pm_clk_add(), but pm_clk_add_clk() (which takes a "struct clk *" directly). Hence print the actual clock name in addition to (and not instead of; thanks Grygorii Strashko!) the con_id. Note that the clock name is not available with legacy clock frameworks, and the hex pointer address will be printed instead.
