Subject: ath9k: mark wmi_event_swba as __packed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e70eb8092754fa92a249f0ed1bc40ab7639b850;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ath9k: mark wmi_event_swba as __packed

The other structures in wmi.h are already marked this way.
Without this marking, we get an unaliged access panic in the tilegx kernel:

Starting stack dump of tid 0, pid 0 (swapper) on cpu 35 at cycle 198675113844
