This clock provider uses the consumer API, so include clk.h
explicitly.

Soren Brinkmann 19f15a3000 staging: clocking-wizard: Handle invalid clk in notifier
Even though it should never happen, handle the case that the clock
notifier is called with an unexpected clock handle. This avoids the
compiler warning:
   drivers/staging/clocking-wizard/clk-xlnx-clock-wizard.c: In function 'clk_wzrd_clk_notifier':
>> drivers/staging/clocking-wizard/clk-xlnx-clock-wizard.c:99:6: warning: 'max' may be used uninitialized in this function [-Wmaybe-uninitialized]
      if (ndata->new_rate > max)
         ^

Devendra Naga 5f18611038 staging: clocking-wizard: check for a valid clk_name pointer
The clk_name gets the return value from kasprintf (part of which does the
allocation of the returned buffer). So check the return pointer
before using it for clk_register_fixed_factor.

Soren Brinkmann 4baa70f69d staging: clocking-wizard: Contain macro argument in parenthesis
A macro doing some arithmetic to calculate a register offset, did not
contain an argument to the macro in parentheses, potentially leading to
unexpected results when using that macro with arithmetic expressions as
argument.
