clk: nxp: lpc18xx: Initialize clk_init_data::flags to 0 Failure to initialize this flag to 0 by default can result in stack junk filling the clk_init_data structure and weird things happen. Joachim noticed that the critical clk feature started triggering for these clks causing boot failures, when it really shouldn't have happened: BUG: scheduling while atomic: swapper/0/0x00000002 CPU: 0 PID: 0 Comm: swapper Not tainted 4.6.0-rc6-next-20160505-00001-g5c8320450d1c #826 Hardware name: NXP LPC18xx/43xx (Device Tree) [<2800be81>] (unwind_backtrace) from [<2800b22f>] (show_stack+0xb/0xc) [<2800b22f>] (show_stack) from [<2801ea21>] (__schedule_bug+0x2d/0x44) [<2801ea21>] (__schedule_bug) from [<281dc937>] (__schedule+0x3b/0x268) [<281dc937>] (__schedule) from [<281dcbbb>] (schedule+0x57/0x64) [<281dcbbb>] (schedule) from [<281de8ef>] (schedule_timeout+0xfb/0x120) [<281de8ef>] (schedule_timeout) from [<28030fcd>] (msleep+0xf/0x12) [<28030fcd>] (msleep) from [<28165a6d>] (clk_creg_32k_prepare+0x1f/0x24) [<28165a6d>] (clk_creg_32k_prepare) from [<281620d5>] (clk_core_prepare+0x1d/0x36) [<281620d5>] (clk_core_prepare) from [<2816340b>] (clk_register+0x22f/0x318) [<2816340b>] (clk_register) from [<282b06c9>] (lpc18xx_creg_clk_init+0x55/0x84) [<282b06c9>] (lpc18xx_creg_clk_init) from [<282b0149>] (of_clk_init+0xc1/0x12c) [<282b0149>] (of_clk_init) from [<282a665d>] (time_init+0x15/0x20) [<282a665d>] (time_init) from [<282a457d>] (start_kernel+0x169/0x274) [<282a457d>] (start_kernel) from [<28008025>] (0x28008025) bad: scheduling from the idle thread!
