From: Daniel Vetter Date: Fri, 9 Dec 2016 18:53:06 +0000 (+0100) Subject: dma-buf: Update kerneldoc for sync_file_create X-Git-Tag: android-x86-7.1-r1~6^2~39^2~9 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=0af23e49316d7870b8f2550a72052bf7d608f230;p=android-x86%2Fkernel.git dma-buf: Update kerneldoc for sync_file_create commit 24a367348a017555f982a9ee137070a7a821fa97 upstream. This was missed when adding a dma_fence_get call. While at it also remove the kerneldoc for the static inline helper - no point documenting internals down to every detail.
