URL: https://github.com/apache/nuttx/pull/16177

   ## Summary
   
   This fixes a crash in the boot in non-smp mpfs configurations.
   
   The alignment of the ctrlreq was correct by luck, and was broken when the 
spinlock was added to the structure.
   
   In non-smp configurations the spinlock_t is 8 bits, which changed the 
alignment of the ctrlreq.
   
   ## Impact
   
   Impacts only MPFS targets where CONFIG_SMP is not set. Fixes a system crash 
in usb driver for those targets.
   
   ## Testing
   
   Tested on a custom HW and on Microchip MPFS Icicle kit (icicle:hwtest 
target).
