There are same conditions for checking whether supporting clkscaling or not. When ufshcd is supporting clkscaling, active_reqs should be decreased by one.

/**
* ntfs_attr_search_ctx - used in attribute search functions
* @mrec: buffer containing mft record to search
* @attr: attribute record in @mrec where to begin/continue search
* @is_first: if true ntfs_attr_lookup() begins search with @attr, else after
*
* Structure must be initialized to zero before the first call to one of the
* attribute search functions. Initialize @mrec to point to the mft record to
* search, and @attr to point to the first attribute within @mrec (not necessary
* if calling the _first() functions), and set @is_first to 'true' (not necessary
* if calling the _first() functions).
*
* If @is_first is 'true', the search begins with @attr. If @is_first is 'false',
* the search begins after @attr. This is so that, after the first call to one
* of the search attribute functions, we can call the function again, without
* any modification of the search context, to automagically get the next
* matching attribute.
