Analyze and fix the following issue in the Linux kernel code: cxl/core: Fix potential payload size confusion in cxl_mem_get_poison()
Problem Details: A recent change to cxl_mem_get_records_log() [1] highlighted a subtle nuance of looping calls to cxl_internal_send_cmd(), i.e. that cxl_internal_send_cmd() modifies the 'size_out' member of the @mbox_cmd argument. That mechanism is useful for communicating underflow, but it is unwanted when reusing @mb...
