095bb8ba45 nvmem: sunplus-ocotp: release otp->clk before return 
Smatch reports:
drivers/nvmem/sunplus-ocotp.c:205 sp_ocotp_probe()
warn: 'otp->clk' from clk_prepare() not released on lines: 196.

In the function sp_ocotp_probe(struct platform_device *pdev), otp->clk may
not be released before return.

To fix this issue, using function clk_unprepare() to release otp->clk.

874dfbcf21 nvmem: sunplus-ocotp: drop useless probe confirmation 
Printing probe success is discouraged, because we can use tracing for
this purpose.  Remove useless print message after Sunplus OCOTP driver
probe.

1066f81563 nvmem: sunplus-ocotp: staticize sp_otp_v0 
The "sp_otp_v0" file scope variable is not used outside, so make it
static to fix warning:

  drivers/nvmem/sunplus-ocotp.c:74:29: sparse:
    sparse: symbol 'sp_otp_v0' was not declared. Should it be static?
