Commit 265b07df758a ("clk: Provide managed helper to get and enable bulk
clocks") added devm_clk_bulk_get_all_enable() function, but missed to
return the number of clocks stored in the clk_bulk_data table referenced
by the clks argument.
That is required in case there is a need to iterate these clocks later,
therefore I couldn't see any use case of this parameter and should have
been simply removed from the function declaration.
The first patch in the series provides devm_clk_bulk_get_all_enabled()
variant, which is consistent with devm_clk_bulk_get_all() in terms of
the returned value:
> 0 if one or more clocks have been stored
= 0 if there are no clocks
< 0 if an error occurred
Moreover, the naming is consistent with devm_clk_get_enabled(), i.e. use
the past form of 'enable'.
The next two patches switch existing users of devm_clk_get_enable() to
the new helper - there were only two, as of next-20240913.
The last patch drops the now obsolete devm_clk_bulk_get_all_enable()
helper.
