Subject: [PATCH v3 0/3] clk: provide new devm helpers for prepared and enabled clocks

Hello,

this is a brown paper bag version (aka v3) of my series adding
devm_clk_get_enabled() et al.

Changes since v2 (sent with Message-Id:
20210301110821.1445756-1-uwe@...ine-koenig.org):

 - send it from the right email account to have the sender matching the
   SoB line
 - make __devm_clk_get static
 - fix EXPORT_SYMBOL usage

The last two were found by the kernel test robot.

Range-diff can be found below.

Best regards
Uwe
