Subject: mt76: mt7615: add __aligned(4) to txp structs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=13602c9d20cda52f84c193bd669174ce338a841b;p=linux.git

mt76: mt7615: add __aligned(4) to txp structs

The beginning of the struct is guaranteed to be 4-byte aligned, and this
attribute allows the compiler to generate more efficient code
