nvmem_cell_read_variable_le_u32 is only defined when CONFIG_NVMEM
is set, otherwise we end up with this build failure:
drivers/soc/qcom/cpr.c: In function 'cpr_populate_ring_osc_idx':
drivers/soc/qcom/cpr.c:814:23: error: implicit declaration of function 'nvmem_cell_read_variable_le_u32' [-Werror=implicit-function-declaration]
814 | ret = nvmem_cell_read_variable_le_u32(drv->dev, fuses->ring_osc, &data);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Select the framwork from Kconfig.

A fix should have already landed for this error. See the patch:
https://lore.kernel.org/r/20210830083449.1.I38e95343209fe1f808c3b4860795a00a2b539701@changeid
...and Greg has applied it. I got a message 6 days ago saying it was in:
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.
That being said, if people think that we should _also_ select NVMEM
for this driver then I have no objections. The use of nvmem in this
driver predates my patch.

It's there, I was still testing on -rc1 when I made the patch and only
verified that all my patches still worked on rc2 before sending them
out, but did not cross-check whether a different fix was applied.
