misc_minor_alloc was allocating id using ida for minor only in case of MISC_DYNAMIC_MINOR but misc_minor_free was always freeing ids using ida_free causing a mismatch and following warn:

misc_minor_alloc is changed to allocate id from ida for all minors falling in the range of dynamic/ misc dynamic minors

Sorry, but no, do not hide behind a gmail.com address. Either fix your corporate email system to be able to send patches out, or use the other method of sending from a different address as documented in the kernel documentation.
As it is, I can't take this, sorry.
Also, only patch 1/2 showed up, what happened to patch 2/2?
thanks,
