Hi Arthur,

I'm thinking we should remove the desc size check in ufshcd.c entirely.
Just read any descriptor with a maximum size of QUERY_DESC_MAX_SIZE .
For user space queries, ufs_bsg reads data of the maximum length and
returns the requested length data. Thus can improve code readability
and save CPU cycles, also can fix your concern.

I don't know how about others' opinion?

Kind regards,
Bean
