Subject: [SCSI] FlashPoint: fix off by one tests
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5d7ebb9c7a04d29efce1099024944dfd94d9f63c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] FlashPoint: fix off by one tests

The check on MAX_SCSI_TAR should be >= instead of > or we could go past the
end of the array.

Joe Eykholt aslo correctly points out that the check on MAX_LUN should be
>= as well.  That matches with how it is used in the rest of the file.
