6.13-stable review patch. If anyone has any objections, please let me know.

From: Sungjong Seo sj1557.seo@samsung.com
commit 59c30e31425833385e6644ad33151420e37eabe1 upstream.
If there is no error, get_block() should return 0. However, when bh_read() returns 1, get_block() also returns 1 in the same manner.
Let's set err to 0, if there is no error from bh_read()
