Subject: s390/virtio: change virtio_feature_desc:features type to __le32
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb317002ab4419ae7e068bee6897f2d5745aa3b9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

s390/virtio: change virtio_feature_desc:features type to __le32

The feature member of virtio_feature_desc contains little endian
values, given that it contents will be converted with
le32_to_cpu(). The "wrong" __u32 type leads to the sparse warnings
below.
In order to avoid them, use the correct __le32 type instead.

drivers/s390/virtio/virtio_ccw.c:749:14: warning: cast to restricted __le32
drivers/s390/virtio/virtio_ccw.c:762:28: warning: cast to restricted __le32
