[PATCH v5 2/3] ata: libata-eh: Simplify reset operation management

Damien Le Moal
2025-07-16T02:05:36Z

Introduce struct ata_reset_operations to aggregate in a single structure
the definitions of the 4 reset methods (prereset, softreset, hardreset
and postreset) for a port. This new structure is used in struct ata_port
to define the reset methods for a regular port (reset field) and for a
port-multiplier port (pmp_reset field). A pointer to either of these
fields replaces the 4 reset method arguments passed to ata_eh_recover()
and ata_eh_reset().

The definition of the reset methods for all drivers is changed to use
the reset and pmp_reset fields in struct ata_port_operations.

A large number of files is modifed, but no functional changes are
introduced.
