Subject: [PATCH 4.19 020/131] kernel/gcov/fs.c: gcov_seq_next() should increase position index

From: Vasily Averin <vvs@...tuozzo.com>

[ Upstream commit f4d74ef6220c1eda0875da30457bef5c7111ab06 ]

If seq_file .next function does not change position index, read after
some lseek can generate unexpected output.
