[PATCH 04/17] media: staging: atomisp: fix string comparation logic

[Mauro Carvalho Chehab]

it makes no sense to use strncmp() with a size with is
bigger than the string we're comparing with.

Fix those warnings:

    drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c:776 
atomisp_open() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 32)
    drivers/staging/media/atomisp/pci/atomisp2/atomisp_fops.c:913 
atomisp_release() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 32)
    drivers/staging/media/atomisp/pci/atomisp2/atomisp_ioctl.c:2751 
atomisp_vidioc_default() error: strncmp() '"ATOMISP ISP ACC"' too small (16 vs 
32)
