Subject: nvme: zns: Simplify nvme_zone_parse_entry()
X-Git-Tag: v6.15-rc1~166^2^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=945e82633ecfd54015d2447a9ba05941665db2ee;p=thirdparty%2Fkernel%2Flinux.git

nvme: zns: Simplify nvme_zone_parse_entry()

Instead of passing a pointer to a struct nvme_ctrl and a pointer to a
struct nvme_ns_head as the first two arguments of
nvme_zone_parse_entry(), pass only a pointer to a struct nvme_ns as both
the controller structure and ns head structure can be infered from the
namespace structure.
