Subject: staging/bcm: move IOCTL_CHIP_RESET case out to its own function.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6e5781c67dfc0946cb53baa0cb034a12925911dd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging/bcm: move IOCTL_CHIP_RESET case out to its own function.

bcm_char_ioctl is one of the longest non-generated functions in the kernel,
at 1906 lines.  Splitting it up into multiple functions should simplify
this a lot.
