Dominique Martinet 05ecc53f94 mmc: core: Fix switch on gp3 partition ... [ Upstream commit 4af59a8df5 ] Commit e7794c14fd ("mmc: rpmb: fixes pause retune on all RPMB partitions.") added a mask check for 'part_type', but the mask used was wrong leading to the code intended for rpmb also being executed for GP3. On some MMCs (but not all) this would make gp3 partition inaccessible: armadillo:~# head -c 1 < /dev/mmcblk2gp3 head: standard input: I/O error armadillo:~# dmesg -c [ 422.976583] mmc2: running CQE recovery [ 423.058182] mmc2: running CQE recovery [ 423.137607] mmc2: running CQE recovery [ 423.137802] blk_update_request: I/O error, dev mmcblk2gp3, sector 0 op 0x0:(READ) flags 0x80700 phys_seg 4 prio class 0 [ 423.237125] mmc2: running CQE recovery [ 423.318206] mmc2: running CQE recovery [ 423.397680] mmc2: running CQE recovery [ 423.397837] blk_update_request: I/O error, dev mmcblk2gp3, sector 0 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 [ 423.408287] Buffer I/O error on dev mmcblk2gp3, logical block 0, async page read the part_type values of interest here are defined as follow: main 0 boot0 1 boot1 2 rpmb 3 gp0 4 gp1 5 gp2 6 gp3 7 so mask with EXT_CSD_PART_CONFIG_ACC_MASK (7) to correctly identify rpmb Fixes: e7794c14fd ("mmc: rpmb: fixes pause retune on all RPMB partitions.")
