[PATCH AUTOSEL 4.19 09/25] net: ftmac100: fix endianness-related issues from 'sparse'

[Sasha Levin]

From: Sergei Antonov <saproj@xxxxxxxxx>

[ Upstream commit 9df696b3b3a4c96c3219eb87c7bf03fb50e490b8 ]

Sparse found a number of endianness-related issues of these kinds:

.../ftmac100.c:192:32: warning: restricted __le32 degrades to integer

.../ftmac100.c:208:23: warning: incorrect type in assignment (different base types)
.../ftmac100.c:208:23:    expected unsigned int rxdes0
.../ftmac100.c:208:23:    got restricted __le32 [usertype]

.../ftmac100.c:249:23: warning: invalid assignment: &=
.../ftmac100.c:249:23:    left side has type unsigned int
.../ftmac100.c:249:23:    right side has type restricted __le32

.../ftmac100.c:527:16: warning: cast to restricted __le32

Change type of some fields from 'unsigned int' to '__le32' to fix it.
