Subject: staging: r8188eu: replace N_BYTE_ALIGMENT macro with PTR_ALIGN
X-Git-Tag: v4.9-rc1~119^2~338
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fb1134087568dad2b974669ebcee09718b7fdc80;p=karo-tx-linux.git

staging: r8188eu: replace N_BYTE_ALIGMENT macro with PTR_ALIGN

PTR_ALIGN is a bit shorter than N_BYTE_ALIGMENT.
