It wasn't easy to find the commit. First I figured out at which path that file
was stored. Using git log -S'wm8962_reg[WM8962_MAX_REGISTER + 1]' I quickly
determined that the file was somewhere in sound/, more specifically
sound/soc/codecs/wm8962-tables.c. However a 'git log --
sound/soc/codecs/wm8962-tables.c' did not show any commit. That was strange,
because 'git log -S'WM8962_MAX_REGISTER + 1' --name-status --
sound/soc/codecs/' clearly shows that the file existed at some point in the
past. The commit is hidden from a simple 'git log' due to 'History
Simplification'. See the git-log man page. I added --full-history -p to the log
command, and searched in the pager for '6fa98e'. That revealed the commit which
references that blob:
git log --full-history -p -- sound/soc/codecs/wm8962-tables.c
