Subject: [MIPS] Cleanup inode->r_dev usage.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=79e55bcf24ad8f31c3021b6ef21c4ce054fe4e38;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[MIPS] Cleanup inode->r_dev usage.

imajor()/iminor() should be used instead of accessing r_dev directly.

Based on patch from Eric Sesterhenn (snakebyte@gmx.de).
