[PATCH] clk: ti: Fix some errors found by static checkers

From: Stephen Boyd
Date: Tue Mar 01 2016 - 13:55:09 EST


drivers/clk/ti/clk-814x.c:34:12: warning: symbol 'dm814x_adpll_early_init' was not declared. Should it be static?
drivers/clk/ti/clk-814x.c:58:12: warning: symbol 'dm814x_adpll_enable_init_clocks' was not declared. Should it be static?
drivers/clk/ti/adpll.c:465 ti_adpll_recalc_rate() warn: should '__readw(d->regs + 20) << 18' be a 64 bit type?
drivers/clk/ti/adpll.c:945 ti_adpll_probe() error: we previously assumed 'd->clocks' could be null (see line 921)

The last one looks like a real bug because we don't return an
error on allocation failure.
