Analyze and fix the following issue in the Linux kernel code: kconfig: document oldnoconfig to what it really does in conf.c
Problem Details: As 67d34a6a391369269a2e5dba8a5f42cc4cd50231 said, the make target 'oldnoconfig' is a misnomer. It doesn't set new symbols to 'n', but instead sets it to their default values.

Analyze and fix the following issue in the Linux kernel code: regulator: max8907: fix use of possibly NULL idata
Problem Details: If a regulator is not used by a board, it's quite legitimate not to provide platform data or a device tree node to configure it (i.e. regulator_init_data). In that case, during MAX8907 regulator's probe(), the idata variable will be NULL for that regulator. Prevent dereferincing it. If the MBATT regul...
