[PATCH] staging:slicoss:slicoss.h remove volatile variables

From: Vikul Gupta

I am a high school student trying to become familiar with the opensource process and linux kernel. This is my first submission to the mailing list.

I fixed the slicoss sub-system. The TODO file asks to remove volatile variables - also, checkpatch.pl warnings included volatile variables.

I removed "volatile" from the variables /isr /and /linkstatus/ in the header file, because they are not needed. The two variables are used in the slicoss.c file, where /isr/ is used as function parameters, string outputs, pointers, logic, and one assignment, while /linkstatus /is used as pointers, logic, and one assignment. All but the assignments will not change these variables, and the assignment does not warrant a volatile qualifier.

To make sure the changes were correct, I ran the files with checkpatch.pl again, test built it, and rebooted it.
