Subject: ps3disk: passing wrong variable to bvec_kunmap_irq()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93055c31045a2d5599ec613a0c6cdcefc481a460;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ps3disk: passing wrong variable to bvec_kunmap_irq()

This should pass "buf" to bvec_kunmap_irq() instead of "bv".  The api is
like kmap_atomic() instead of kmap().
