Hi Mauro, After merging the v4l-dvb tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/staging/dt3155v4l/dt3155v4l.c: In function 'dt3155_start_acq': drivers/staging/dt3155v4l/dt3155v4l.c:210:2: error: implicit declaration of function 'vb2_dma_contig_plane_paddr' drivers/staging/dt3155v4l/dt3155v4l.c: At top level: drivers/staging/dt3155v4l/dt3155v4l.c:321:2: warning: initialization from incompatible pointer type drivers/staging/dt3155v4l/dt3155v4l.c:325:2: warning: initialization from incompatible pointer type Casued by commit ba7fcb0c9549 ("[media] media: vb2: dma contig allocator: use dma_addr instread of paddr"). I have used the v4l-dvb tree from next-20110921 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
