Subject: PM / Hibernate: Swap, remove useless check from swsusp_read()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=09c09bc618a4ceec387c57542031b4fc35826e16;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

PM / Hibernate: Swap, remove useless check from swsusp_read()

It will never reach here if the sws_resume_bdev is erratic.
swsusp_read() is called only from software_resume(), but after
swsusp_check() which would catch the error state.
