RDMA/hns: Add hr_reg_write_bool()
In order to avoid to do bitwise operations on a boolean value, add a new register interface to avoid sparse comlaint about "dubious: x & !y" when calling hr_reg_write(ctx, field, !!val). Fixes: dc504774408b ("RDMA/hns: Use new interface to set MPT related fields") Fixes: 495c24808ce7 ("RDMA/hns: Add XRC subtype in QPC and XRC type in SRQC") Link: https://lore.kernel.org/r/1624262443-24528-4-git-send-email-liweihang@huawei.com Signed-off-by: Lang Cheng <chenglang@huawei.com> Signed-off-by: Weihang Li <liweihang@huawei.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
